Simple solder spool holder. Designed for a Felder 250g spool, but will fit anything up to about 55mm wide and a diameter of about 70mm.
Uses a 8mm rod and two 608 bearings. Print one body part, the two sides and two axis stops (I used PLA, but anything will work. No supports needed). Use threaded inserts on the side parts.
Place the spool on the threaded rod, add the two axis stops (the need M3 screws), place it with the bearings into the side parts and screw everything together.
