Rubbergun for children for looms printed in one peace

Since my first try of making a rubbergun for looms i have worked more with onshape to create some technical parts. Its working fine. The gun can just shoot 2 looms. I have to improve it.

Have a look at onshape:

There are two versions:

light and solid

Have fun.
