here we have a ball bearing. i needed one, so i made one. feel free to use this for whatever project you need it for. they come in handy!

i recomend printing this quite fine. the .16 preset worked well for me. but id imagine it would only get better the finer you print. anything above about 18, the balls get murged together. keep that in mind. i recomend lubing these to get it running as smooth as possible. i used one drop.

Happy printing!
