filament spool holder / rack

Filament spool holder to organize filament spools on a shelf. uses 2 - 5/8in dowels included are 2 ends and a middle section so the dowels dont sag in the middle. my dowels are 4ft long and hold 16 filament spools. you can use shorter dowels if you dont need that much storage. i printed a half foot for the middle but you could just print a 3rd full size foot for the middle. *** i recommend printing them on their side as supports are a bugger to take off if foot is printed standing up.
