I was fascinate from the marble clock (from Görkem Bozkurt). So I would linke to build my own one. I do not have a 3d printer until now, 1 plan to buy a 3d printer, perhaps the “Prusa i3 mk3s”.

Based on the innovative rolling ball clock design created by Harley Mayenschein back in the 1970s, this awesome 3D-printed variation is yours to make at home, courtesy of free online instructions.

The Manifold Clock Kickstarter project embraces the mathematical concept of Riemann surfaces to create an artsy 3D timepiece that expresses time through shape and movement.

The Plotclock is a small, 3D-printed clock that forgoes the traditional gears and springs for servos and an Arduino microcontroller. It writes the time. And then erases it.
