Spool Stand

A spool-stand (roller) for spools for any axis-diameter.
You need some additional material as there are:
16 M8-Nuts
1 m threaded rod M8 (8 mm)
4 standard ball bearings (best is abec 11) for inline scates

I modified the axis because of some poor grip between spools and axis. The axis is best printed in vertical stand, but sometimes breaks apart from the heatbed because of extruder-vibration. Therefore I applied four struts which stabilizes the work-process in a reliable way (see photo). Just crack them away like normal support.
