Cannon(Working)

This is a print in place fully 3D printed launcher no assembly needed. It can launch a BB bullet over 10 feet and can launch anything that fits in the .5 inch diameter barrel. Just put something in the barrel pull back the plunger on the bottom and let go. The cannon can pivot up and down a little bit on its base as well.
