Ball Bearing Ender 3 Spool Holder Remix

thingiverse

Remix of the genial idea from Scarpantes Since the internal ring of the ball bearing couldn't enter the spool holder of my Ender 3, I enlarged it to 36,5mm and added two spacers. Some remarks: Print it with the best settings possible (I used 0,4mm nozzle, and 0,12mm layers) in order to have the best smootness Some sanding is required in order to ensure the lower friction possible Wash everyting after the sanding Do not use oil. If there is some friction, sand and wash the parts more. The spacers are designed not to touch in order to avoid printing seams of the inner bearings Turn on the offset feature in the slicer, in order to avoid elephant foot. I didn't and that resulted in more sanding I recommend to glue the spacers and the internal ring to the spool holder. You never know when the spool holder is going to fall on the printer. I added two lids of two dimensions (I used the 60mm one). Those are optional and are meant to be attached to the external 52,5mm ring of the external bearing in order to prevent the spool to fall. It happened to me and spoilt a 10 hours print. Luckily didn't spoil the printer. But after that the only way to changhe the spool is by unscrewing the spool holder. The other external ring measures are on the Scapanter's project.
