I wanted to replace a missing portion of a foam-dart gun. The gun was supposed to have a giant belt of darts, but it was missing the belt and cover, so I made a model to fit into the existing hinge that would bolt to a piece of 2" ABS pipe and let me store some electronics while making the gun look complete.
I printed the hinge, but it failed, which was not a problem because the printer completed enough of it that it still worked. I installed the part inside a short tube that I decorated with a black-and-white sticker. A Thingiverse user created the black accessory rail at the top, but I printed two segments together to form a coupled unit.
I made several revisions to the battery grip to run wires more efficiently. The first one squished one of the wires between it and the chassis pipe. The new revision has gaps to pass everything without pinching. I had to print at a slight angle with supports after a vertical copy failed, but it was a faster method.
I broke up my soldering tasks into three days. I started with the emitter array, which consisted of the LED ring, infrared emitter, transistor, and a resistor. There were two, so I started with the older model, which I drilled a hole in to make way for the light ring wires. However, the updated model already had a hole in the printed version. I installed the supporting components mid-wire and used shrink-tube on all the exposed copper. To finish the day, I soldered the USB connectors I use on the back of the taggers.
I needed a rail-mounted battery holder, so I designed rail mounting parts with no extra features and a battery holder without the curve for mounting on a chassis pipe. The print took six hours, and one of the rail mounts was misprinted. I also created a hole-drilling guide to assist with mounting the emitter arrays and USB ports.
Biting Comic's Ben joined us to promote Shark of War and discuss Robocop. We were delighted by his choice because the movie aged better than any of us expected, and it was shockingly progressive for 1987. The movie handled some tricky subjects with appropriate satire and candor.
The rest of the summary posts have been arranged by date.
