A large marble run that has three switching paths. There is a hand crank at the top for you to spin. When you spin the crank, and there are marbles at the bottom, they will get taken back up to the top to go through the track again. It has three parts
By the way yours will be all one color
1. the marble run.
2. the screw.
3. the handle
I provide 10 marbles for the run. The design is from Mroek; link to the original design: https://www.thingiverse.com/thing:1340784
I made a change to the top handle for the crank; here is the new handle:https://www.thingiverse.com/thing:5742657 by redoano
