Blowback and shell ejecting rubber band gun (Sig Sauer P226)

Used PLA and it holds up well.
Printing took quite some time.
Assembly, especially making the slide slide well, did take quite some time.

I also increased the rubber bands by about 2x to get increased blowback forces.
Works nicely now.

Awesome project, nice printing files.

I did not use glue (only grip-shells) in order to dis- and reassemble the whole thing for adjustments.

BBU could probably get some improvements to allow for bigger tolerances and allow easier re-engaging into slide-hook.
