These printed a lot better than I imagined! I printed PLA with 5 walls and it seems super strong. Printed with Bambu 0.20mm Strength settings

great file, I modified it in Solidworks to make a hole for the clock mechanism. This was a gift for a friend, and this file allowed me to skip designing it myself.

I honestly love this very much. its the perfect cross between abstract art and real-world grounded demonstrations of STEM principles.

these spin very nicely, I've even had friends ask for one themselves

fits the bearings nice and snug
