Marble Roller, Stackable

thingiverse

This is stackable marble track/roller I designed and printed for my niece and nephew. There are 3 sections: - Catch is the bottom Piece to gather the marbles (ball bearings) - Section A has a loop, small jump and long track. - Section B has a Rotating spiral, Seesaw and rails. The sections can be placed in any order. This design is stackable so I could design or print more sections to make it taller. There are 3 different tracks per section, the marble falls down the posts to the new section. I used 9.5mm (3/8") bearings. Short Video of it is here: https://youtu.be/Hn45CC4XuK4 Note: The "_asc" named files are just ASCII versions of the files, the others are binary. Choose whatever works best for your slicer.
