Spool Holder for Gladiator 4" Racks
thingiverse
I designed this holder to accommodate the majority of filament spools and fit snugly within a Prusa print bed's confines. Using PETG with 20% infill provided sufficient structural integrity for my purposes. While I wouldn't advise printing this in PLA, feel free to experiment if it suits your needs. No support is required to achieve a successful print.
