Step files for "Space Violin", a handheld rail based test rig

All the hardware is modeled in the step file, you'll need some M3 heat set inserts, 5mm dowel, and 8mm flat head and cap head m3 fastners. MGN12 200mm with an H block.

Current build is using a single F695 bearing on the large idler, this is optional for smooth running and many other bearings could replace it with changed size holes.
