I have seen many gyro toys on ThingiVerse. However they are not child safe, i.e. they will not survive children throwing them around. So I designed this with a joint which prevents from gyro rings slipping out.
The center is a small globe, which will let it spin horizontally like a spinning top. It also has a small Archimedean spiral.
I printed with supports, but you can skip it if your printer supports it.
2018-Jul-9 : Edited to give little more clearance in first circle.
2019-Aug-6 : Added v4 with 90 degree pivots.
Design
Fusion 360 its mostly parameter driven, so the thickness, height etc can be changed easily.
The author marked this model as their own original creation. Imported from Thingiverse.
