REmixed Spool holder for ender 3 v2 or ender machines. i used a pin in the end of the spool so the spool could sit flat on the bed and be printed without supports. i mounted mine on top of my enclosure with stock filament spool holder arm. uses 2 608ZZ ball bearings. Printed in PLA. for the pin and spool and nut for printed 100% infill. .2mm height. supports were used for body. body was printed with 4 perimeters and 4 top and bottom layers @ 40% infill. may need to play with slicer settings for pin to fit in spool perfectly. i used super glue to hold in place. My horizontal expansion setting was set to -0.15 for this print and it seems to be ideal for spool and spool pin.
