Infinity Marble run

Due to the constant up and down movement, this ball spins in circles for an infinitely long time and looks extremely satisfying. The whole operation is very quiet and works on battery power without any annoying cables. You can adjust the speed with a screwdriver without unscrewing anything. And you can switch the whole thing on and off by simply pressing a button at the top.

The print only requires support for one part, and it is very easy to remove. You can print the whole thing with just 2 printing plates on an A1mini.
