designed this spinning top using 2 Australian 50cent pieces and a 6.35mm steel ball .
video shows it spinning for over 2 and 1/2 minutes before it falls off the table top.
I have at times able to get it to spin over 3 minutes but wasn't recording at the time. please leave your times in the comment if you print this out.
you'll find the STL's here https://cults3d.com/en/3d-model/game/...
lets see who can get the longest spin time!
