Hanging Spool holder

I could not find a suitable hanging spool holder for my enclosure so I've designed a new one. The spool is mounted on the hangers using this thing: https://www.thingiverse.com/thing:2070272.

I've designed two versions of the hanger, version 1 is the shorter one and can hold 1kg spools. Version 2 is longer and can fit 2 kg spools (e.g. Prusa ngen filament). In order to get the two sides with the slot facing in the same direction you must mirror one side. The sides can be printed without supports.

The M8 nut knobs for fixing the spool on the holder have hexagon holes for M8 nuts. I've also included the nuthole tester STL which is a small part with equally dimensioned hexagon hole so you can quickly test the fitting of your M8 nuts and adapt the extrusion if the fitting is too tight or too loose. The nut knobs require supports on the hexagon hole.

The optional spacer frame can be used for an easier mount of the hanger sides. After screwing on side in place you can use the spacer
