Fidget Gyro Spinner V1

Yet another Fidget (fidgit) spinner from me!!
This one has an extended "tower" in the middle to use a string to get some high speed spins... Just like a pocket gyroscope.. Bearings are standard 608 skate bearings for the weights, and a 607 hybrid ceramic for the central hub..
The central "mushrooms" are sized for the 7mm Hybrid Ceramic bearing, and use an M3 x 20mm screw to clamp, so would probably be fine with am 8mm standard skate bearing.. I'll do an 8mm version if peeps want it!!
Printed in my usual PET-G filament...
