Ender 3 Attachable Spool Holder with 624 Ball Bearings (v2)

An Ender 3 spool holder so the filament spool does not grind down the existing spool holder and rolls smoothly.

You will need 4x 624 ball bearings and some glue (epoxy is best) to glue the halfs together if they do not press-fit.

If the clips are slipping attach them to the existing holder with double sided tape.

With this the spool moves so smooth i didn't notice it moving most of the time, no vibrations, no sound, no jerking.

Print in 0.2mm layers with 2mm walls with support structure.
