Hi everyone! This is one of the easiest-to-print and best bearings, and it works great with old BB pellets from old BB guns! :) I use these bearings for various purposes, from upgrading printers to creating functional prints! If you need help adjusting the size, please let me know. However, all three sizes should work well, and the tension or clearance between the three sizes may vary slightly!

I hope it will work as well for you as it did for me!
