Disc Shooter v2.7

A derivative of several other Things, this is the latest version of my Open Source Disc Shooter. I haven't designed an interlocking case yet, but assuming this revision works I will. The OSDS has a funny looking handle, but that was so that it would fit on the build platform. It could easily be extended by clamping a handle around it.

Update: Replaced problem STL's with fixed versions.
