The model is meant to be used for storing PET strips ( strips of plastic made from plastic bottles) with a width of 8mm.

This is a remixed version, and compared to the original model, it should hold a PET strip from a 5L watter bottle (the original can hold 2.5-3L bottles) , the part where you clip the plastic strip for spooling should be more robust, and should take less filament than the original model (if scaled to the same size that would allow to hold 5L watter bottles PET strip).
