Description
A marble run system for 11mm ball bearings.
The extras collection can contain anything :).
Please see the Starter Set for a full description, photos, printing notes, and links to the complete system.
Supports are required when printing the cap block.
The 'cylinder tool' object's purpose is to smooth out any holes in other blocks that are not perfectly round.
