3 kg spool holder (fully printed)

I initially had a cantilever arm for 3 kg spools, but probably skimped on the infill so it sagged. I finally threw together a four-roller design that can accommodate 1 (~203 mm diameter) and 3 kg (~250 mm diameter) spools, and there's a version that SHOULD be able to accommodate 5 kg (~300 mm diameter) spools, if my googling was accurate. OBJs included if they weren't for you to modify.

Length of the body pieces should be about 175 mm for smaller printers.
