Marble Roller, Stackable

thingiverse

I designed and printed this stackable marble track/roller for my niece and nephew to enjoy. The design consists of three separate sections that can be placed in any order: - Catch is the bottom piece where marbles (ball bearings) are gathered. - Section A features a loop, small jump, and long track. - Section B includes a rotating spiral, seesaw, and rails. Each section has three different tracks for the marble to follow. The marbles fall down posts from one section to another. I used 9.5mm ball bearings in this design.

Choose the one that works best for your 3D slicer software.
