spool holder for ender3
Description
a spool holder for ender 3 designed for low material printing (print time is 3hours, frame 30% infill spacers 70% infill), more stable as 1 axis support ones, min inner spool diameter is 48mm max 75, designed for use with 3pcs 626 bearings (6x6x19) and M6x15screws (I used some 20mm ones) UPDATE> I reconsidered the use of 608 bearing and figured out this would make not much sense ,one actually may use printed wheel from PLA instead of bearing ...as far as the shaft is a metal screw the friction is low ..added wheel.stl :)
