Semi Auto Rubber Band Gun

This is a ratchet action style semi auto rubber band gun. It's designed for 6 bands but they tend to tangle on each other when packed that close. In my testing it works best with 3 or 4 shots. Started as a project for a side arm in the ongoing nerf war.

Print area on my setup isn't sufficient to print the barrel. Stronger/cheaper/easier to just dremel some slots into a wooden dowel then try and make it multi section. The two wooden rods need to be squeezing together a bit tight for the ratchet to work.
