I'll see if I can get a simple easy to print Space Shuttle uploaded. Should I just get the Orbiter, or each individual part (Orbiter, External Tank, 2x Boosters) in one file?
1 file for each part that is separate. So if the 4 parts 4 files. Scale does not matter because we usually use Blender to scale, but the files do need to be manifold, and GPL.

Ran the toolhead into the build platform at an early attempt to print the Holy Probe.
