Voronoi spool holder

I was dissatisfied with the original spool holder, so I designed my own, which also looks a bit more interesting. The holder is rigid and features two support points with rolling bearings and a threaded pin inside the roller. Bill of materials: 2x 608 bearing (or any with ~22 mm O.D)1x threaded pin M8 (length 115 mm)2x nut M86x M4x20 screw6x M4 nut
