This is just a spinner for the extruder on a 3D printer. I have the MP Select Mini with the MK8 extruder but it should work with most. It’s my design in that I remixed it as the original didn’t quite work. I just made the shaft thicker on this one.

I really like the open honeycomb design of this spinner…
This one is called planetary gears I believe, found it over on Thingiverse and it does work well and looks neat.
Here’s another Biohazard spinner fidget, but this one didn’t work out well. The bearings just fall out and I found out you need to glue them in, I don’t like the idea of gluing them in. The creator of the spinner actually says you need to glue them in place, nope, I like being able to remove them. It is a nice looking spinner though.
So this is a neat spinner, you print the top and bottom separately and then put the bearing in one side and squeeze together.
My son likes Destiny, so I made a Destiny themed spinner..
Yep a biohazard themed fidget spinner…
