Top 35 3D Printed Gun Accessories to Make in 2023

With the accessibility of 3D printing technology now greater than even a few years ago, it is possible for more people to print more things than ever before. Printers used to cost a user several thousand dollars. Now you can get a small one for around $200. With the ease of use, it is a small wonder that gun owners are turning to 3D printing. Plastics have become so durable and usable that you can even use your printer to make parts for your gun, so having a 3D printed accessory for your non-3d printed gun is nothing to snicker over. From grips to stocks and magazine stackers to shell holders, getting an accessory for your gun is as easy as pressing print and saving money.

Ready To Start Making Your Own Gear?

Here is the 3D printer we recommend for beginners who want something easy to set up and learn, but with the capacity to make some pretty large items. Coming in at under $200, it’s a steal.

This 3D Printer can print all the accessories listed below and more. Here is the best price we’ve found on this 3D printer.

Winchester/Remington/Mosburg Pump Forend

Shotguns are one of the most popularly owned guns in existence, and this 3D file for a pump forend grip will fit most shotguns in the main three manufacturer linups. This is a full length pump forend that can replace an existing forend.

You can check out this 3D file and see more example photos here.

3 Size Picatinny Rails

While there are a couple other picatinny rail options below, I found this newer version that comes with a standard 3D print file containing 3 common picatinny rail sizes. You can create all three sizes in a single print which speeds up other alternatives below.

When printing a rail, you’ll want to be sure to print with an extra hard filiment like PETG, which costs approximately $19 a spool. This filiment will be harder than other printiong materials and hold onto your accessories much better while maintaining a snug fit.

Pistol Magazine Holder

Among the best gun accessories are those that help you organize and keep track of ammo and magazines. This Pistol Magazine Holder is a great wall-mounted solution for hanging your magazines for easy access. Once you print out the rack, all you will need to acquire is the hardware to mount it on your wall.

This holder works with magazines for:

  • Walther PPQ Q4 TAC
  • CZ Shadow 2
  • Glock 19 Gen5 MOS
  • Beretta APX

Any type of plastic filament will work with this design. With this type of magazine rack, you do not need to fuss with magazines scattered in boxes and on your floor. The designer used PETG with a 20-30% infill. Once you have printed it, you will need to purchase some countersunk wood screws to mount it.

Magpul Pmag AR-15 Magazine Coupler

A magazine coupler is a great accessory to have for your AR-15. It joins two magazines together keeping a full magazine at the ready while the other magazine is in use. This makes for quicker reload times and with a magazine that could not be more accessible. It is literally at your fingertips and usable with a simple twist. Now with the Magpul Pmag AR-15 Magazine Coupler, you can print your own 3D coupler to use. This straightforward but effective design that tightens down on the clips works specifically with Pmag 30rd magazines. In order to make this design work, you need only to add:

  • One #10-24 3 inch long bolt
  • One nut

Once you have the pieces that you need, you simply slide the coupler over the middle of the two magazines you want to join and tighten the screw.

M-Lok Stubby Grip

This is a short grip that is designed to work with an M-lok rail system. With this grip, you can add an extra, secure hold onto your M-lok compatible rifle. Once you have printed it out, you only need the necessary hardware, two bolts, to attach it to the M-lok system. This is an STL file and a cubic pattern with support of 20% and an infill of 50% or more.

For this cool little accessory, the grip:

  • Has grooves on both sides of it for a secure hold
  • Angles back about 15 degrees to make it a little more comfortable

To print it, you can use an Ender 3 printer (which is what the design was originally printed on) or the printer of your choice. Also, for this grip, PLA is a usable material, but it is recommended that you use ABS because it is a more stable material.

Dual Magazine Holder

Originally designed to be used for competition shooting, this belt loop magazine holder could work for a variety of belts given the hole dimensions of 1.65 inches by .25 inches. It was designed to carry Smith and Wesson .45 magazines, but could likely work with other .45 magazines of similar dimensions. Printed for toughness at 80% infill using PETG, this design requires that you go to your hardware store to get:

  • A retention spring
  • A 6/32” x ½” screw
  • A heat-set insert.

With this stout design, you can print your own magazine holder for quick reloading with your .45 pistol whether in a competition setting or simply in a practice setting at home or at the range.

Remington 870 Pump Forend

Sometimes accessorizing your gun means adding a part that works better for you than the original part. Such may be the case with this 3D printing of a Remington Pump Forend which can come with rectangular slats for a solid grip or as a smooth sleek attachment. And it not only fits the Remington but also:

  • Mossberg 500 series
  • Winchester 1400
  • Winchester 1300
  • Winchester 1200

This accessory has supports and requires infill of at least 35%. PETG is probably the ideal filament although PLA works fine as well. In an early version there was not quite enough room for the castle nut, but that has been fixed in later versions.

Ruger MKII Charging Handle

This is a printable bolt racker that works for a Ruger MKII that could save a retail price of about $30 for an aluminum one. With nubs at both sides of the opening, this charging handle is sort of like a can opener for guns and can be kept just as close as your real can opener.

  • You do not need to leave it on your Ruger
  • With a hole through the handle, you can tie it to a rubber bracelet around your wrist

The opening is 1.75 inches and the tool works well made from PLA. It does not need support, but requires an infill of 50%. If you use a plastic that tends to shrink a lot after printing, then you should scale up the size a little. Some minor fitting may be required after it has been printed.

7.62×39 100 Round Case

This one requires a large printer. If you have one, then with this file you have the ability to make your own ammo case out of ABS plastic. This is huge savings overtime. Given how much ammo you store and use, being able to make your own cases for it could lead to a great benefit and ease of use. This case:

  • Carries 100 rounds
  • Prints as one piece (hence the large printer)
  • Cuts the round size into the lid

With the label already engraved into the case, you have a nice way to organize and store your ammo. This download does come with a minimal cost of just under $4, but that still makes for a savings. If you print this out:

  • Use .02 layer height
  • No infill
  • No supports or brim

300 Blackout Trimming Feature

If you are in the practice of trimming your own shell casings, then you know that part of the problem is over insertion leading to trimming off too much. That is where this nice little accessory comes in handy. This is a printable plastic jig that holds the shell in place for you to trim it to a predesigned length.

A simple design, this jig is a solid piece of plastic made two with shell stops:

  • At the base of the shell
  • At the shoulder of the shell

Using this jig your cut will be true everytime. It was specifically designed to fit into the vise of a 2 inch mini chop saw from Harbor Freight. Because of the tension this little piece will receive from vise and from shell to say nothing of the cuts from the saw, print this accessory out of hard and durable ABS.

30-06 20 Round Carry Case

Here is another great carrying case for you ammo, particularly your 30-06 rounds. Most gun owners use this round at some point in their lives, so having a case to store what you have around is essential. This case prints as one piece with a 302 mm width (even though it holds 20 rounds instead of 100), so you will need a large printer to print it.

This download also has a minimal cost of around a buck fifty. Not bad for a closing case that holds 20 rounds of ammo that closes on hinges and has a small clip to hold the lid shut. If you print the case:

  • Use .02 layer height
  • No infill
  • No supports or brim

Rusty Lok

This is an alternative to the metal tek-lok devices that enable you to attach gear to your belt. These are very popular items for both gun and knife owners since it allows them to attach whatever gear they need to their belts. Now you can print your own in durable plastic (such as ABS) and use it to hold:

  • Shot shell caddies
  • Mag carries
  • Other ammo carriers that you need at your belt

The only thing the maker recommends that you not carry is your actual gun. This is not intended to be a holster of any kind (though you will find one later in this article if you keep reading).

This is an item that relies on durability so print it with at least 50% infill, but you could go all the way up to 100% if you felt the need. Once you have printed it out, you will need to drill the holes using a 3/32 bit for the dowels to slide into place. Use ⅞ long dowels with 3/32 diameter.

Trigger Lock

This trigger lock is a very simple device and the kind of accessory where 3D printing really shines. Making devices like this enable you to save a little bit of money here and there that adds up over time. It also removes any excuses about investing in the safety of your firearms. Held in place by a simple counter sunk screw and bolt, the trigger lock fits over the trigger providing safety and security for your weapon. For the nut size you can use 10-24 or 10-32 with your favorite tamper proof screw of choice.

As far as printing, ABS is recommended for this one but other plastics would work. After you choose what you will want to work with, use:

  • .2 layer height
  • 20% infill
  • 3 bottom layers
  • 4 top layers
  • 3 walls

M&P Shield Flat Trigger

This little accessory really shows off the world of plastic in terms of:

  • Use
  • Strength
  • Versatility

It also shows off 3D printing’s ability to work with small and detailed pieces. This accessory is not a trigger guard, but the trigger itself. Printed with fine detail (including some etching work to give it some flair) and extra strength around the pin for durability, this is meant to be a flat trigger for a Smith and Wesson M&P. The creator of this remarked that the shape of the trigger helps not jostle the nose of the pistol while pulling. Now is a good time to reinforce a truth about working with plastics and 3D printing. These are not manufactured pieces, they are fabricated by you. So use care when making them and caution when employing them.

M-Lok Angled Foregrip

This foregrip is designed after the Nightstrike Diamondback foregrip and has a similar function, being something the shooter can grip at the front of the rifle. It also has two positions on it:

  • One where you can hold it like you would a rifle stock
  • One where you can grip it like a pistol

The designer made this for a PSA AK-47 but it will work with any M-lok rail system. For this model:

  • The size is X 114 x Y 51.9 x Z 19.1 mm
  • Use an infill of 50% or greater

Installing this grip can create more versatility in how you hold your fire arm, and it can relieve your pocket book of brand name purchase.

Ruger Magazine Thumb Saver

This great accessory is a key chain thumbsaver that will go with you wherever your guns go (so long as it stays on your key ring). Slide this thumbsaver over the magazine while you are loading it up and it can save the wear and tear on your fingers for the grip and the trigger.

Designed for Ruger magazines, this thumbsaver works with the following models:

  • 24/45
  • 24/45 Lite
  • MK IV
  • MK III
  • MK II
  • MK I

Printing this accessory does not take any supports or rafts. You can make a very solid piece with a 100% infill, but you can also dial it back to 25% infill for just as much durability for what it does. It all depends on how much give you want to put into the piece and how much you think you will be using it.

Laser Polar Alignment for Astro Tracker

This is probably one of the most intricate designs that this article has discussed. In this accessory, you can align a metal laser sight for a gun to a polar alignment. This mount holds the laser sight steady while allowing it to be adjusted rotationally by means of a 6806 ZZ ball bearing through the use of an aligning app. So cool! This printable definitely has some assembly required, but the technical assistance it can give you with your sight should make the extra effort well worth it. You will need these additional parts:

  • Two 12 mm M4s
  • Four 20 mm M4s
  • Six M4 shims
  • Two of the bearings mentioned above (or you can use two 61806 2RS ball bearings)
  • One laser gut sight of your choice

The printing aspect of it will keep you busy and give you lots of practice with your equipment since you will be printing out the following parts:

  • One body
  • Two legs
  • Two caps
  • Two lids

Finally for printer settings, note that this printing uses supports with 100% infill, and you can work with PETG material.

Trap Shooting Shell Holder

Shotgun shells are a pain in the butt to wrangle, but with this shell holder, you can keep them literally right by your side, easily accessible, and organized. Because the holder is made to the dimensions of the shells, you can line them up the direction that makes the most sense to you when you grab one to load it. This holder is as straightforward as it looks. With angular openings throughout to give a see through feel that allows you to judge how low your shells are, and printed with an easy going 10% infill this box is:

  • Light
  • Easy to use

You can even just cut the top off your box of shells and slide it in there if you want to. Even though durability is not explicitly called for, ABS tends to last longer in the sun than PLA.

Round Forend Molot Vepr-12

This is another forend piece, but instead of it being a grip for pumping rounds in a shotgun, it is round and encloses the barrel of a Molot Vepr-12. It is 245 mm long and can fit on barrels from 483 mm.

This is a fairly simple accessory that is easy to install on Weaver rails with a couple M4 screws. For printing this accessory:

  • Use supports
  • No rafts
  • 25% infill
  • You can use PETG

Walther P22 Gun Stand

This gun stand is a great accessory for your Walther P22 or other guns that are of a similar type (the piece that holds the gun in place is a little loose to allow for some flexibility). For example the P99 fits on this holder. With this accessory, you can hold:

The holder organizes all these things in one place, which is a huge benefit, but the way it does it, with the Walther and the clip standing upright, makes a great display for the gun and its components. So under the right circumstances, the simple, black holder can make a show piece out of your gun (safety first, of course). You can print it with a height layer of .2 mm and use PLA for the material. For all it does,this is actually one of the easiest accessories to print out.

Flame Cover M4 V1

A flame cover can be an important accessory for a gun, but would a plastic flame cover really cut it? Yes! This Flame Cover M4 V1 is designed for an M14. Because the plastic materials used in 3D printing are hard and because they are, in this case, not exposed to flame for long periods of time, they can work (though probably not as long as metal). Nevertheless at 7 grams this flame cover is significantly lighter than its metal counterparts. The printer settings are straightforward in this case, and if you want to print this accessory you can use a PLA material or greater with a .2 of accuracy. You should also use 65% infill.

MagPul PMag Rack Organizer

This is a truly useful accessory for gun owners, it is a magazine rack organizer. You can print out multiple racks and use them for three magazines each, as long as they are AR-15 magazines. The design of these organizers is simple and yet remarkably versatile in how you can mount them. Putting them in the interior of your gun safe, you can mount them on:

  • Floor
  • Walls, including vertical and horizontal positions
  • Ceiling

Either way you have only to slide the bottom of the magazines into the rack and gravity will take care of the rest. These are great for getting magazines up off the floor or the shelf of your gun rack. Each rack has four holes so you will need to install them with #4 countersunk wood screws. Not only does that make your magazines easy to access, but the computer files for the printable racks allow versatility to print for one, two, or three magazine racks. With versatility in both the design and the application, this is a must have accessory.

Sunshade for a Bushnell 1x30RD

Protecting the accuracy and visual clarity of your scope is a must even if you do casual shooting, but especially if accuracy is crucial to a hunt or competition. That is why this accessory Sunshade for the Bushnell 1x30RD is a must have item. This is a bit unusual compared to the accessories that this article has already looked at because it does not so much depend on the durability of a hard plastic as on flexibility. That is why, in this case, the sun shade (which slides onto the end of the Red Dot) is made from a softer, more flexible TPU filament.

This accessory is easy to print out and supports the following file extensions:

  • .sldprt
  • .sldasm
  • .slddrw
  • .stl

Glock Grip Plug

A grip plug is an important accessory for a glock. It prevents the magazine from snagging when it is being put in, and it also prevents dirt and debris from getting into the gun from the handle. This plug is made as a trim and snug fit so that it sits flush with the frame of the gun, looking like it is an actual part of the weapon. One of the nice things about printing 3D components and accessories for guns is that you have the opportunity to adjust them as you need to for your particular firearm. Simply take a knife and trim and go to work as necessary. SO fear not if the plug is not the perfect fit at first.

Glock Holster

Another accessory that you can print out for your Glock is a holster, believe it or not. Using a durable plastic and a solid design, a printed 3D holster can actually work well and fit sleekly to your belt. It has that sort of look where the Glock is just sitting on your belt. This particular design was made for the Model 17 and supports a variety of file types. If you are not wanting to print your holster, we recommend this one instead. You will need to print out components and assemble them with some store bought hardware, including:

  • 4 mm diameter pin
  • 2 screws with nuts
  • A spring

This design also comes with your choice of three different types of attachment catches:

  • 40 mm for extended and for belt
  • 25 mm for molle standard

USP HK Flashlight Mount

This is a cool accessory that allows you to mount a 20 mm long flashlight to the USP rail. Who wouldn’t want a flashlight mounted to their pistol? It fits snugly against the trigger guard with just a bit of extension past the barrel and has easy access to the on/off switch. Now you can print one out from the following files supported:

  • Solidworks
  • STL

With this single printout all you need is a screw and a nut that fits flush to the mount. The designer admits that the install is somewhat tricky. This sounds like a necessary development of the design. Early models broke, so the inner rails of the mount are reinforced. So while the install may be tricky it is definitely achievable.

CZ 75 Aluminum Style Grips

Complete with the CZ logo, these grips look like aluminum, but are actually, you guessed it, plastic. With a cool flashy design, they look great and are easy to install with just a couple store bought screws.

Also, these grips work on the following models:

The grips also feature a place to put grip tape.

Full size Glock 17

This full-size 3D printed Glock 17 is perfect for practice and live-action scenarios. A full-size replica like this works for practicing your draw, getting perfect sight picture, and many other drills that are safer with a full-size dummy gun.

Pistol and Magazine display/holder

Keep your gun ready when needed while looking great. This combo allows you to safely store your gun upright with extra magazines at the ready.
Due to the gun remaining upright in the holder, it’s extremely easy to grab quickly and throw the in next to the handgun.
