Marble Genius Spacer

This is a connector for the Marble Genius play set. Use it stand-alone or as the base for creating parts. Spacing is 100mm center-center for short parts or 200mm for the long ones.

Update 7/2/2019:
Updated to v4. Changed the thickness of the walls to match a multiple of 0.4mm nozzle size. Was getting tired of how my slicer was handling the other one.
