I found making the nuts into hex-nuts makes the spin effect more satisfying. Please check out Gijs' original design and show some support. The included .gcode was generated for the Mk3S, the nuts use more filament to give them some weight.
2/2/2022 Update: I've expanded the models into different sizes and lengths. Some of these may be challenging to print successfully, so be sure you've got a well calibrated machine.
Cheers!
