Spool Rack

thingiverse

A stacking rack that uses a 25mm curtain pole to hold filament spools. Simply print two of these, add 25mm curtain pole tube (available anywhere and online) then join them together. You can print a further set and it will stack on top of one another! Using this, I no longer need to mount individual spools to the printer, I can pull the filament down straight in the extruder from the spool rack making it much easier to swap out filaments.
