Get your 3D printers started with Taccom’s free downloads

3D printing and firearms – a very sensitive subject!

One of the main reasons why people are afraid or against it, is because it’s a new technology and new inventions tend to drive the uneducated into forbidding it (much easier than trying to understand what’s going on). It’s new, so it must be dangerous – and we need new laws!

3D print is “new” in terms of now being affordable to everyone. I realized yesterday that even Apple sells 3D printing machines in their online shop.


Ultimaker 2+ 3D Printer in the Apple Shop


Did anyone ever consider that most, if not all, firearms parts are already produced through some sort of computer aided design, and CNC machines or lathes are used sometime along the production?

So if you have the CAD file you can produce almost any firearms related parts. With various quality, of course, depending on your skills and machinery.

And if you don’t have any of these machines, you can find inspiration from Pakistan.

But if it’s illegal to own a lower, upper, barrel, bolt or whatever the local laws dictate, it’s illegal regardless of the method used to produce it.   Just. Don’t. Do. It.


The difference between an affordable 3D printing machine for home use and a professional one is, for starters, several hundreds of thousands of dollars. Obviously there is going to be a difference in quality of the parts that the printer can produce. However, even cheap machines can do some clever stuff.

Taccom, LLC in Minnesota USA produce a lot of interesting parts for firearms, especially shotguns, rimfire and AR-15s.

They have a page with a lot of fun downloads, so if you own a 3D printer you can download their design and start producing

The downloads can be found here:

I have a hard time imagining that any of these parts would be illegal anywhere.

However, I’m sure they can improve your firearm and aid you in your next competition.


On their Facebook page they recently wrote:

As promised…in our free download area….the design that IS the Short Range Tactical Sight. We hope to be coming out with this in an adjustable design and and made out of aluminum…..but until then, down load it, print it out slip it on your top rail……you WILL be impressed with how fast it is and how accurate it is as well. This was designed after the express rifle sights used for dangerous game in Africa. We suggest that you use black filament to print this out and then either a white or yellow paint for the front sight ‘dot’. Please let us know how it works for you!!

PS…….I’d suggest printing out a couple extra……It’s a printed part!! Probably may not take a barrel hit. But the good news is, it’s free and SUPER easy to replace!!


Tim Ubl, the owner of Taccom and his background:

I’ve been in the firearms industry in one form or another for over 20 years. Back when I was 8 years old, my father would take the family out to an old gravel pit and we would spend the afternoon shooting up clay pigeons with model 67 Winchester .22RF rifle. My son now is the proud owner of that very rifle rifle and he learned shoot using it.

I entered into shooting competition years later and being a designer by trade, I used my skills to develop many shooting accessories that are being used by alot of the top shooters today or adapted by police or military operations, infact you are shooting competitively or are in law enforcement, it is possible, that in a way, that I’ve helped you through a match or made your job a little easier. Working for various companies gave myself more exposure to the shooting industry as well as the police and military sector of that industry. I’ve decided to take the huge step of starting my own company to further develop and offer some of the most innovative shooting accessories available. This is a family business and we’ll strive to give you the best value for the dollar, and sensible, usable products and no gimmicks.”



A few years ago, I tested printing an AR-15 magazine. I’m not sure this was the latest revision of the CAD, but it was built in a high-end 3D Systems SLS machine (nylon).

Below you can see Magpul PMAG, 3D print SLS, Lancer and random steel magazine in comparison.


Took the spring (and follower?) from the Magpul. I reckon it would be very difficult to print a spring.


End product below, note the oil and dirt from my rifle.

How did it work? Fit was excellent, but function was not too good. The lips were too thick, so I had to manually sand down the thickness and as I did this there was a problem with the strength. At last it would fire perhaps 5-6 rounds. So it works, but there’s room for improvement.



I haven’t tried any of Tim Ubl’s CAD files, and please note he had nothing to do with the magazine I printed.

    • Guns from scrap

      You can buy spring wire on Amazon and make your own spring

      You will have to print out a 3d from to wrap the spring around, Then heat it up till it turns blue and quench it in water

    You underestimate California and New York.

    • Erik B

      True, true…

    • Nunya Bidniz

      Or the idiocy of someone trying to sneak an entire plastic-printed NAA mini past the Thousands Standing Around. Sure, it would likely blow up in your hand if you managed to somehow sneak ammo aboard the flight too, and I doubt very much that even if it *didn’t* blow up in use, that the barrel would manage to stabilize the bullet, but still, that’s got to take some sort of prize for “Bonehead Move of the Week.” ::)

      • Wow!

        Hell, just sneak in a factory firearm. They always miss them. Thousands Standing Around. Lol. I’ll have to remember that.

  • noob

    clever to set this up. DEFCAD is too controversial. Thingiverse has a strict “no weapons” policy.

    There was market demand, so this now supplies.

    Plus the evolution in design will be very fast with open source designs being iterated over by a crowd of people.

    The new large diameter E3D-v6 Volcano nozzle and innovative high strength filament like Nylon blend and chopped carbon fiber/nylon blend could be amenable to very interesting parts.

    How do they avoid ITAR violations? Can’t this be downloaded across the globe? What about foreign nationals downloading with the US? I’m not against this, but I’m curious how one reconciles the law in light of this activity.

    • Ambassador Vader

      ITAR has been cracking down on a lot of this. I remember not too long ago the state dept. went after Defense distributed and made them take down a lot of files, however they immediately were released on torrent sites and other file sharing sites. Just goes to prove when ever the gov’t is telling you that we have to put a stop to file sharing because of all the piracy, it isn’t because of the kids downloading music, it is to control the flow of information they can’t control.

    • roguetechie

      If ITAR were a law designed to do anything but hurt American domestic manufacturing and end users I’m sure people would care more…

      But it isn’t, so we don’t.

      • iksnilol

        Funny but true. IE I’d like to buy some American silencers and optics. But can’t due to ITAR despite both being unrestricted in Norway.

        • roguetechie

          Yup, it really is a law specifically aimed at the American people and American companies.

          One more in a long line of laws designed specifically as end runs around both the first and second amendments in order to curb, hamstring, and or outright make arms production and thus arms acquisition by the American public inaccessible.

          Combined with other import bans and etc it’s extraordinarily clear what the true aim is in all of this.

          First rule of being an officer, never give orders you know won’t be followed….

          Being a lawmaker is no different, if you make punitive, asinine, and clearly obstructionist laws designed to deny your people the rights you literally SWORE TO UPHOLD upon taking office is bound to result in people doing everything possible to subvert said laws.

          It also damages the social contract which holds societies together, and makes it exponentially more likely that even good laws will begin to be ignored…

          Gee, none of this has ANYTHING to do with how election 2016 went down at all…. Nah, white peoples juss be rayciss!!!

          • iksnilol

            Ummm. ITAR affects me who isn’t AMerican or in America. I just want some Primary Arms scopes and a SilencerCo Sparrow :/

          • roguetechie

            Yup, it sucks for other people too…

            However you’re a recipient of secondary blowback suckage, whereas the American public are recipients of primary direct fire suckage effects….

            Think 60mm mortar landing IN your foxhole versus 60mm mortar landing in the next foxhole over.

            Best post I’ve seen this week…maybe this month…possibly this year.

      • Michel_T

        Making sense of government regulations… isn’t that an exercise in futility?

        Government agencies have no qualms with smuggling automatic rifles south of the border. They literally give away guns to this or that foreign government.

        But for a reason or another they won’t let a US company sell me some scope mounts unless the said company pays big $ for an export license…

        • roguetechie

          Even worse than that, they’re intent on making more and more domestic American manufacturers pay ITAR fees regardless of whether they have “export privileges” at all.

          It’s a huge p art of crushing home based and non full time FFL’s as well as artificially erecting new barriers to entry to compensate for the rapidly dropping costs for tooling capable of low volume manufacturing tasks.

          Except unlike the tooling costs you OWE whether you manufacture one or 100,000 or even NO parts that year… You still OWE!

          They make the mob look fair, even handed, and FORGIVING.

  • roguetechie

    Also, what was commercial grade 3d printer territory 3 years ago is now within reach of cheap diy desktop 3d printers now.

    The materials selection and even the actual 3d printing process selection available for under $5000 has EXPLODED!

    it’s really pretty amazing what can be done now with very affordable machines and free software.

    Also, defcad is perfectly safe and has a jaw dropping amount of very awesome, iteratively refined, and entry level printer compatible designs for a truly amazing number of items.

  • kregano

    It’d be nice if they said what some of the non-obvious parts are for. Like, what’s the bolt release button for? Benelli shotguns?

  • That +10 Glock extension looks awesome. I think it’s going to be my first PETG print.
