I was home with my kids while my wife was out of town and my 7 year old was really pushing me to print stuff out. He picked out a rubber band gun, but I did not think it was a very well designed. I printed it out, but was still on the hunt for a better design. I found one, but thought it could still be improved. Here’s a link to the gun I ended up making.
