Filament spool hanger / double-sided

I attached the main hanger to the wall using standard 6mm drill screws.

The weight of two filament spools, even 2 kg of Prusament, is not much for three screws. Between the axle and the track, I attached two metal ball bearings of the appropriate diameter with a small amount of glue. The track is placed on the axle with the bearings.

The track fits easily onto the main mounting, there is no need for a tight fit, especially as the interior is not perfect, so that disassembly is easy. After installing the roll, remember to tighten the locking nut. I am sharing a version for regular 1kg rolls and an extended version that fits the 2kg Prusa spool. I mounted the whole thing above my current printer. It is possible to print TPU from this hanger. Made from PLA, which is inexpensive and hard. No special material is required if the conditions are right. Dysza 0.4mm.
