This is a miniaturization (roughly 1:10 scale) of the mighty Marble Machine X by Wintergatan. At this time, it is unfinished, as I've decided to remake it, but I will release this design if anybody wants to finish it. It was originally intended to work similarly to a programmable music box, but since the clearances are too loose, everything rattles around. All of the functional parts move.
At its current state, the gears mesh and the sun gear freely rotates. There are no belts or pulleys to connect the handle to the planetary gears. Everything prints without supports except for the axle supports and the marble divider, but I have not printed that, so print at your own risk. I machined the flywheel out of some washers stacked together and glued with JB Weld and tapped so that the pulley will bolt onto it. After that, a Delrin bushing fits through the pulley and flywheel. The axles are made of a 5/32" steel drill rod, but you might be able to get away with printing them. All screws are m3 size. The frame is superglued together, so make sure to print it out of PLA.
I suggest printing the frame out of PLA since superglue adheres very well to it.
