Black Hole Spinner

The Black Hole Spinner: a well balanced, eye catching spinner for the fidgety engineer.

This is my first shot at designing a fidget spinner and after doing a number of prints, I am quite pleased with it. It's well balanced, versatile, and eye catching.

I included two versions: one with a fillet around the outer edge, one without. Both look great when finished.

It's compatible with 608 bearings of any type, but I highly recommend the Bones Red bearings. I cleaned mine out with WD40 followed by a an isopropyl alcohol bath and got it to spin for about 1 minute 30 seconds. The bearings can be pressed in with a vice (I used a Pan-A-Vice for mine). Once there in there, they stay put and are unlikely to come loose unless you're hit by a truck. Do not tap the bearings in with a hammer, especially if you choose to print in PLA. Seriously, DON'T DO IT.

If you have any suggestions, drop me a comment. I'm always open to constructive criticism. Stay fidgety!
