Filament holder

Filament hanger I designed for heavier rolls.

The design is definitelly not polished but it works. I used adhesive tape to ensure better fitting of the bearings and rollers. This is probably not necessary (you secure the assembly with a threaded rod and nuts, so it does not seperate no matter what), but without the tape the fit is not very tight and during roll change some parts can separate.

Intended to hang on the frame of an enclosure such as this one:

The frame pipes are 19,5mm diameter and have flat and wide connecting hooks, hence the shape of the mounting holes.

You will need 2 sides, 2 rollers, 2 ball bearings and a threaded rod to secure the assembly with nuts. The rod has to be around 300mm long, hole in the roller is 8,6mm in diameter.

For ball bearings I used 16007 ZZ CODEX 35 x 62 mm (such as these: https://allegro.pl/oferta/lozysko-kulkowe-16007-zz-codex-slowenia-35x62x9mm-127423767
