If you're going to make a Fidget Spinner then why not make one which might just bring you some luck, here we have the 4 leaf clover fidget spinner.
Designed with Fusion 360 the spinner body starts off as an SVG, this is then extruded to the size you want and the depth will be the depth of the spinner bearing which in this case was 7mm and it's a 22mm Diameter bearing.
The edges of the clover are filleted as far as it would allow me to go which was approximately 1.4mm
The bearing size is sketched in and extruded using the cut tool and then a dummy bearing is sketched in and extruded so we can then make the finger pads on which the bearing rotates.
All in all a nice little project.
Thanks for looking and be lucky!
