CR30 Side Mount spool roller

Ball bearing spool holder to mount on side of CR30 belt printer. A remix of sorts, inspired
by the Creality CR-10 Bearing Filament Spool Holder.

I used the Extrusion profile 20x20 V-slot Customizer to make the v-slot profile.

Adjust the spacing between the 2 frames for the diameter of your spool, and slide
the front roller brackets in/out to adjust for spool width.

You will need to print:
- Left & right frames.
- 2 long pins (frame bearing mounts).
- Left & right front bearing mounts.
- 2 short pins (front bearing mounts).


In addition you will need
- 12 M5x8 button head bolts.
- 12 M5 T-nuts.
- 4 608 bearings.

Optionally print a pair of the extrusion end caps.
