3-D blueprint for rifle used by Adam Lanza removed from Thingiverse

By | December 19, 2012, 6:21 PM PST

After the tragic mass shooting at a school in Newtown, Conn., last week, 3-D printable guns probably seem like a really bad idea to a lot of people.

Which probably explains why the plans showing how to create the parts for the AR-15 assault rifle, the type of gun platform that Adam Lanza used at Sandy Hook Elementary, have been removed from Thingiverse, a clearinghouse of digital designs to create real objects.

And if you’re thinking, “Wait — 3-D printable guns. That’s a thing?” Why, yes, actually, this fall, the idea of a 3-D printable gun not only was out there, but demos on how to create them were distributed online and a collective called Defense Distributed tried to raise money on crowdfunding site Indiegogo for its Wiki Weapon Project, whose goal was to create a fully downloadable printable 3-D gun. (Its test run produced a gun, actually the AR-15; the trial printed gun broke after firing six rounds.)

While those events in themselves were controversial, the deaths of 20 first graders last week has made the idea of printable guns even more contentious, leading to Thingiverse’s sudden takedown of the AR-15 design listing, which had been up since February 2012.

CNET reports that as of Tuesday, the plans to create a key component of the AR-15 assault rifle existed on the site, available for download:

Those plans, and plans for other firearm components have now been removed from Thingiverse. You can access [Michael] Guslick’s old listing, and you can also find it on the Pirate Bay and elsewhere, but the printable STL files have been removed from Thingiverse, and the listing no longer turns up when you search there.

When asked about the deletion of these files, a Thingiverse spokesperson told CNET: “Thingiverse’s Terms of Service state that users agree not to use Thingiverse “to collect, upload, transmit, display, or distribute any User Content (ii) that…promotes illegal activities or contributes to the creation of weapons, illegal materials or is otherwise objectionable.” If an item has been removed, it is because it violates the Thingiverse Terms of Service.”

Funny how that wasn’t how it felt back in August, when CNET senior Editor Rich Brown pointed out these exact terms of service to Thingiverse and asked why plans for gun parts were available on the site.

Then, the company directed him to the section of the site terms that said, “We reserve the right (but have no obligation) to review any User Content, investigate, and/or take appropriate action against you in our sole discretion if you violate the Acceptable Use Policy or any other provision of these Terms of Use or otherwise create liability for us or any other person. Such acts may include removing or modifying your User Content, terminating your Company Account in accordance with Section 8, and/or reporting you to law enforcement authorities.”

The company has now changed its tune and yesterday sent Brown this note:

“Thingiverse has always been, and is currently, evolving…as is the company as it pursues innovation and growth. We have always had the discretion to take action for policy violations. Recent events served as the impetus here to take immediate action (and there were several) and reiterate or emphasize the site’s focus on creative empowerment for products that have a positive impact.”

If you want to see the rationale behind the Wiki Weapon project, here is a video about it:

I had great respect for this site till now.
there is simply no need to add to the glorification of maniacs and shooters by calling them by name.
'the Sandy Hook shooter' 'the Sandy Hook killer' 'the Sandy Hook gunman' ANYTHING but getting another maniacs name in the public eye.

What nonsense is this?!?!
Lanza stole the AR15 he used, from his mother.. he did not use plans and print off the lower.

SmartPlanet, get your Sh.t together; your stories are increasingly becoming mindless drivel repeated from mainstream "media" outlets. I'm about one story away from unsubscribing and boycotting.

3D Print Does NOT Work
Regardless of drawings 3D printing cannot today produce high tensile strength structures that can sustain the high pressures and temperatures of a firearm and especially a semi-automatic one.

One does not need a 3D printer to build a gun only a few machine tools or if one is really desperate, a home made and simple set up like those used by Berber gunsmiths.

Most young people simply cannot imagine using a machine tool directly instead of a computer.

Sandy Hook Killer.
we all have violent thoughts against people like Lanza but most people know right from wrong but some can not distinguish wrong from self righteous indignation, with the power of the gun condemnation is just a click away, and it all starts with possession, as they would see it is 9 tenths of his law, knowing how we can all be violent I can see how this people would dream of the day that they will use this weapons and all will pay for their rage, as responsible adults is our responsibility to remove temptation from our crazy children and keep a vigilant eye of their increasing violence and put a stop of it, my suggestion is get involve, intervention is a part of an immediate solution, after all is not just about your crazy kids but other peoples kids, education is key to safety!!

I was also wondering
what is wrong with people who are so afraid of things. I think science calls it paranoia.

"Only fools blame tools"
Another ridiculous article crying wolf. You cannot make a gun on a 3D printer. Even if you could, the machine to do it would cost tens of thousand of dollars. real cost effective!

they didn't make the firing pin, the barrel, or any of the other required parts of the gun - those were taken from a gun that was purchased. the parts that they did make fell apart after firing 6 shots. if a SLA grip can't tolerate the recoil, do you think a firing chamber would stand up any better to the explosion that happens inside it? tell you what, i would be afarid to pull the trigger unless the gun was mounted and i had a LONG string.

have you ever heard of a zip gun? the plans are on the internet and all of the parts are available at the local hardware store for a few dollars.

oh, but guess what? in the US making a gun is illegal unless you are a licensed gunsmith.

please quit trying to stir up emotions by slanting stories and pushing your left wing agenda. we will call you on it every time you spin something like this.

"Only fools blame tools instead of human failings. ... Blaming guns for crime is like blaming helmuts for headbutts. ... we all kno [sic] that obesity is a direct result of the proliferation of spoons & forks Get a clue." - Ted Nugent

i agree with the motor city madman. why not stop being PC and let's try to do something constructive like promoting a good home environment. Another good thing to do would be to get some of these nut cases off the streets. every one of the 'bad guys' recently were people that had a few screws loose.
