Mini Rubber Band Gun

Update 7/31/2016:
I added a small piece (underbarrel.stl) to glue under the barrel to make it look more like the original.

This is a 3D printed remix of RBguns' Stepup action rubber band gun. His video can be found on https://www.youtube.com/watch?v=NLb-8ofC3Zk
Trigger mechanism has been simplified.
Trigger springs forward naturally by the tension of the ammunition. Trigger won't return when gun is empty. Time to reload.

This is a small gun so it won't hurt little kids. Sca
