Pinwheel Firework Bearing Holder
thingiverse
If you're one of those people who loves pinwheel fireworks but is constantly let down by their performance, then this project is tailor-made for you! Use a standard 608 bearing and these three-dimensional printed parts to build the ultimate low-friction pinwheel firework mount. Attach the bearing bezel and attach the pinwheel to the hub using various lengths of M3 hardware. You might need to press the bearing in with a vise.

I've only tested it twice, and it worked wonderfully both times, but your results may differ. I take no responsibility nor liability for any damage or injury that might be caused with this device.
