I was making spinners for my boys and ran out of bearings to use as weights. We have a lot of marbles around so modified a couple spinners to use 15.5mm marbles instead of steel weights or bearings.
(Standard Marble size is about 15.5 - 15.7mm)
They are made where the marbles can be changed out if they want to mix or have different colors.
On the curved Spinner I mad a cut so marble can be inserted easily and it is secure.
You can use razor blade of small saw to make the cut.
Just as FYI on my printer I had to print PLA @104% and ABS @ 105% to make bearing go in easier
Enjoy
