I swear I saw something like this ages ago. Some way to hang a bunch of games off of a larger ring to make it easier to transport for a kid. Maybe like a bracelet? Easy to switch between games too.

The cartridges are a pressure fit in these. Use a small double loop keyring to attach to the larger ring.

Print instructions

Usual, 20% infill. Maybe make the ring out of PETG to make it a bit tougher?

No supports required. It will print fine. I'll add some photos soon.

Edit: added holder for Switch cartridges and the .f3d file.
