Hey everyone! This is one of the easier and best bearings to print on your bambu lab printer that works extremely well using old BBs from your old BB gun back in the day! :) I use these bearings for everything from upgrades to my printer to functional prints! If you need help resizing at all let me know but all 3 sizes should work well and all 3 should have a little different amount of tension or space between the bbs!

Hope this works as well for you as it has for me!
