Control Gun (game) with variable barrel

thingiverse

To make the pieces fit nicely Id recommend prinitng pins at around 99,5% the size. I used a 0.6mm nozzle with a layer height of 0.32mm, so print accordingly. Brim were added so complexer surfaces dont lift of the bed that easily.Non 3d printed parts utilized in this build were 2 ball bearings each 22mm in Diameter, aswell as a regular spring from a generic ballpoint pen.
