Thingiverse just took down all the AR-15 stuff.

I guess I can’t blame them for panicking, after all they might have offended someone by well, I don’t know. It’s kinda funny to see this happening, the first amendment is suffering because people are scared of the second amendment. Sure, they’re a private company and can do whatever they want, but this reeks of censorship to me, so I am reposting the STL files I have downloaded over time. If I am hosting your file and you would like me to take it down, feel free to email me so I can tell you to fuck right the hell off.

There’s also the AR-15 magazine:

And the alternate version of the two part lower here

I am sorry I do not have proper attribution for the individual files, and I cannot find haveblue’s STL on my computer.

UPDATE: I found the model originally uploaded originally by haveblue:



Update 2: After being asked, this is the specific email I got when they pulled the file I had uploaded:

I didn’t even bother uploading it here as a printed upper is beyond useless. I only printed it so I could test the fit against my printed lower. They already did this song and dance once before, only to realize that printed gun parts didn’t violate their policy and they put them back up. Either they changed the TOS or they are just scared of public opinion.

    Thanks for re-posting my lower! I’ll see if I can dig up the original SolidWorks file for it, as well as the files for my trigger guard (removing a trigger guard? srsly?)
