Mini Tri-Spinner (+Dual)
By Nicolinux
Your fingers never stand still do they? Mine neither... So I created this miniature spinner using one 607 ball bearing. The other ball bearings are just for kicks and to add weight.
This thing spins forever. From start to standstill it takes at least 90 seconds - not bad!
