Asymmetric Fidget Spinner by monsterguy

Last crawled date: 3 years ago

This uses three different sizes of steel ball with the centre of mass worked out in Fusion 360.
These were just three balls I had in a box of random things, so the sizes are a little inconvenient.
Ball sizes - 19.4mm, 15mm & 12.75mm, which I think means they are really 3/4", 15mm & 1/2". The bearing is the usual 608 style.
I don't imagine many people will have those lying around, but thought someone might like to see this :)
Here's a terrible quality video of it in action - https://youtu.be/554f3f_ORTs
