This desktop marble machine by MaKim Projects features a rotating tower that keeps things rolling all day long. After its steel spheres roll down a series of twisting and spiraled ramps, they return to the top on its illuminated corkscrew elevator. Want your own? The 3D model is available on MakerWorld, with a parts kit for sale on the Bambu Lab store.
