Dual Trigger 12 Round Rubber Band Gun

A dual trigger rubber gun with 12 shots, which is easy to print and doesn't require any screws.

The triggers should be operated separately, and the wheels loaded separately.

Choose one of the 3 barrel options. The short barrel is good for small rubber bands or for little kids. The long one shots stronger but harder to load.

No supports required. Consider placing adhesion pads around wheel spikes and trigger pointy edges if they don't stick well to the bed (attached)

I printed in PLA, at 0.2mm, 40% infill (I set separate infill of 75% for wheels, and 60% for the bottom plate. Not sure it is required), 70mm/s speed. Initial layer at 15mm/s speed, 120% width and 0.24mm height. 

This is an upgrade to this excellent rubber band gun from thingsverse. I changed some geometry and added a second trigger and wheel.
