This is My 12 shot, semi automatic rubber band gun.
I've designed this to be super easy to print, easy to put together and a fun and functional outcome!
The Cog will hold 12 rubber bands, firing 1 at a time (with the single shot trigger) and all off them at once with the auto trigger.
The spring used to rebound the trigger is the spring out of a common click pen, so easily obtainable!
The bolts are M3 x 25mm with nuts.
I hope you enjoy my toy, and feel free to remix it and join in the fun!

Mechanical components are best printed with 100% infill, whereas the gun frame itself is fine with 20 - 30%
