Spool holder onto tube

My spool holder solution
I use home furniture as wall, and PVC pipe as core for filament spool.
On PVC pipe is inserted this spool holder, and is protected by dowel (pin or screw). The groove is place for this pin. I use small amount of lubricant. No bears needed, it works well.

So you need :
- PVC pipe (30mm internal, 33mm external diameter)
- Dowel (pin, or screw) to mount this holder
- Spool with filament
- Lubricant (transparent silicone paste etc.)
