I remixed this spinner to add a ring around the outside. This adds more weight so it will be able to spin longer.

Printing:

Infill: 100% to provide weight and durability
Speed: 40mm/s
Supports: Yes. There are overhangs on the outer tabs

After printing, a 1/4" hex key can be inserted into the middle to help break the gears loose.
Top and bottom caps from the original are included in the files to add a more finished look and feel.
