(Made permanent) Ball Bearing Ender 3 Spool Holder

thingiverse

I really like the bearings that scarpantes has designed, but they need to be taken off every time from the spool to be put onto a new one, and aren't easy to stay on the new spool while putting it in the spool holder. So I made this "add-on" to make all of this easier, allowing to easily remove the spool with the bearings staying on the spool holder, and making it easier to put in the new spool. The 2 files : - original20180817_ball_Bearing_internal_ring.stl - original20180817_Ball_Bearing_external_ring.stl (diameter 57.5 mm) are exactly the same ones from scarpantes, downloaded on August 17, 2018 to make my design. I'm putting them here for compatibility in case the original ones are changed. You have to : - print two spacers - print one tube - have some glue - and maybe have a piece of sand paper to perfect the finish and ensure the gluing process
