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.

A big part of it is being armed with knowledge and some technical chops: the donor PC (from institutional surplus) was a real beast in its day, they repaired a broken SSD (!), and found a miraculously […]
I suffer from mild RSI: a warning to stop, but one that goes away when I do stop. The trigger is using a mouse for extended periods. The alternatives for general everyday computer use aren’t great for my work habits, which center on precise pointing and clicking, so I’m in the bad habit of mousing […]
I got one of those bug-zapping LED lightbulbs, in hopes of murdering the flies drifting into my office during the increasingly warm and muggy Pennsylvania summer. I got mine from Home Depot, but the bulbs at Lowes, Wal-Mart and Amazon are all obviously identical. There are two lights in each bulb: an ultraviolet one inside […]
