Summary

I designed this for a kid who wanted a ninja star/fidget spinner. Enjoy!

You need four 608 standard skate bearings- it's a tight fit so i inserted them with a rubber mallet- no glue necessary.

This would probably be slightly difficult to spin with small hands, but with caps it's easy to spin on a table.

THIS WAS DESIGNED FOR MY PRINTER'S TOLERANCE - YOU MAY NEED TO SAND SLIGHTLY BEFORE INSERTING BEARINGS

Post-Printing

Insert 608 skate bearing with hammer/ rubber mallet... depending on your printer's tolerance you may need to sand out the inside a bit.
