Challenge your 3dprinting skills with this sealed ball bearing.
If your not up for a challenge, if your printer is not perfectly dialed in, if you ca...n not take printing for an hour and ending up with nothing but piece of junk plastic then read no further.
This is something i did as a test for fun and nothing else. Would it work? Yes it does but it aint easy, there is probably a great chance that you will end up with a picece of junk.
If your up for the challenge, go for it! And please post a picture of "i made one" if you get it working! =)
