Caleb sez, "The Department of Defense ordered that 3d printed gun removed from the Internet. That didn't work out. You can still download it and print it.
I did, and found that the files are a mess and not really functional. I also took a cool timelapse video of the printing."
1. the scale on the individual files was way off.
I suspect this has something to do with the printer it was designed for. It seemed very close to being 1 inch = 1 mm. Not a completely uncommon problem. Manually resizing got some files to look right, but I found many simply wouldn’t resize.
2. Almost every single item had errors.
If you’ve done 3d printing, you’ve found that a model can have all kinds of issues that will stop it from printing correctly. I found every single item for the gun had errors. I actually learned a lot about how to repair non-manifold items from this exercise, so it was good in the end.
Some items, like the hammer and the hammer springs simply would not print. I ran them through systems to repair them and fix errors. It would say that everything was fixed, but when I tried to “slice” them for printing, the software would crash. This means that my gun is incomplete. It has no hammer. Not really that big of a deal to me.

If you think that your phone may have been hacked so that your adversaries can watch you through the cameras and listen through the mics, one way to solve the problem is to remove the cameras and microphones, and only use the phone with a headset that you unplug when it’s not in use.
Lured by the internet’s pervasive insistence that it represents a superior, more comfortable typing experience, I recently went back to an old-timey mechanical keyboard. This was a mistake. I am now a hamfisted ASCII jazz disaster.
