Tri-Spinner Fidget Toy 4mm BBs Only

thingiverse

I made my own version using 40 common 4mm BBs from bb guns. I paused the print at 4.6mm or 4.8mm z, inserted 10 BBs into each groove and then resumed. The holes are 8mm and may fit original caps, but I've included my own cap instead. I also included a slightly larger version as well as a slightly smaller one. Additionally, I included a version with balls in it - if you can get it to print okay, that's awesome. Some notes: If your fidget comes out too stiff, try printing it a little bigger by 1% increments until it feels smooth. On the other hand, if it's too loose, do the opposite and make it smaller. You can also spin it with a drill for a while to see if that loosens it up.
