Description
This is a workable toy cannon for the top of my desk. Just put a ball in the end of the cannon pull back the plunger at the back and release. The plunger ball can be unscrewed to take out the firing mechanism and a spring from a ball point pen can be inserted. I made this in tinkercad and has been made public. I will break this apart for a better print.
