Waveball (twistable)

prusaprinters

Sphericon  print as one solid or in two halfs with a connection pin (easier to print and movable).In the script you also find an option to use a revolving circle instead of a waveform, so you could place marbles in the halfs - but may be bit more difficult to print.The halves have holes to put a 10mm filament piece in as a detent only put them in one part not both!
