DESIGN STILL IN DEVELOPMENT - PLEASE DOWNLOAD AND HELP DESIGN

A toy plastic disc shooter powered by rubber bands. Dubbed the "OSDS" as in Open Source Disc Shooter.

I've broken the major components of the toy into design groups as such:
Gun Case files - for the moment this is a straight copy of Sublime's pencil gun.
Firing Pin files - these are the only parts I have printed out.
Disc files - a variety of discs.
Clip files - a draft clip design

The only component I have tested so far is the firing pin, without any actual discs.
