This is my filament support. It is make for fix it on a surface. In my case I need to fix it one my printer box. The axis is just put on the support and can be removed. Two adapters are screwed on each side of the spool and can be removed faster by the central groove. The main axis is terminated with 2 plain bearing for a smooth rotation. It must be sanded and greased.
20% except the master axis at 40%
I print it in ABS and the supports and the master axis slowly .
