Simple Fidget Hand Spinner

A very simple design.
Three bearing spinners don'T get much shorter than this.
Use any standard 608 (skate) bearings.

I recommend you insert the bearings right after the print as ended and the model is still soft on the heated bed. They will go in easily and after the print is cooled down, they wont go anywhere. Also, no sanding will be required.

If you don't insert the bearings when the print is still soft, depending on your printer, you might need little to no sanding to fit the bearings in.
Make sure they fit tightly enough not to slip and not too tigh as to crack the model.

I have made the bore size slightly bigger for my needs. If your bearings are too lose, notify me and I will make an adjusted version.
