Ikea Billy spool holder

Mounting for two rods to the Ikea billy wardrobe, ideal for storing filament spools.Designed for maximum capacity - this mount does not interfere with the spools either in width (they can be from the wall to the wall of the cabinet) or in height (the spools below do not interfere with the upper level) There are two versions:- "center" which locates the spools symmetrically in the middle of the cabinet, the same amount back and forth. Thanks to this, you can store spools larger than the classic 20cm (just mount the rod holder one hole lower, and we have space for large spools, up to 25.5cm in diameter).- "upper" - intended mainly for the top shelf, when you have a wardrobe with doors, the spools placed evenly in the middle would interfere with the wardrobe hinges.
