Ball Snap Fit
At first, I modeled a little piece to test the fitting for 6mm balls to ensure that they would be able to roll around, but not pop out.
Fidget Spinner Model
From that initial model, I made a circular pattern inspired by a perpetual wheel, curious to see how the balls would react on a fidget spinner.
3D Printing
After modelling the piece, I 3D printed the model and placed the metallic balls into place.
