A simple rotating ball cup. I may do some more finalizing on this design but I am quite happy with the results I got (especially for first try).
It is comparable to this product: https://bit.ly/3aaL62L
But is obviously significantly cheaper to make

I printed everything with a .2 layer height.
Ball cup/ring printed with prusament petg at like with 15% infill and no extra shells added. But I probably could of printed it stronger but its not like I am dropping the bowling ball on it.
Pins were printed at solid with prusament petg with supports
Feet were printed solid in ninjaflex tpu
