Ball bearing spoolroller

Spoolroller using 4 standard ball bearings (type 608 8x22x7 mm, eg. from inline skates). It reduces the friction of the spool to a minimum.

For printing you will need 4 of each part and also 4 ballbearings. If you wand to use printed bearings you could try this: https://www.thingiverse.com/thing:2396503 or other approches here on thingiverse (I have not tested them).

Created for the original Anycubic i3 Mega spoolholder (similar modell could be found here: https://www.thingiverse.com/thing:2512933).
