Super smooth ball bearing Ender 3 spool holder
Description
Super smooth filament spool holder for Creality Ender 3 series printers! It uses 608 bearings that can easily be found in fidget spinners, skateboards etc. Designed in a way to utilize the direction of the layers for maximum strength. The main frame and its threaded part need to be printed seperatly and glued together after printing. Used normal superglue for it but most other glues should also work. Printed the threaded parts laying down flat and the bearing supports standing up in 0.16 mm. Used no supports on the threads for better quality and had no issues with the overhangs. The main frame was printed at 0.2 mm layer height, 20% infill, supports enabled and laying down flat so the layer directions gives more strength. Goes especially well together with a sidemounted spool holder for more direct line of flow for the filament for even less restriction for the extruder: https://www.thingiverse.com/thing:4743097
