Alternate Spool-Holder for PrintDry

thingiverse

This is a versatile spool holder for the PrintDry printer. I prefer to dry and feed filament from my PrintDry simultaneously. Flexible materials like NinjaFlex and PVA are extremely soft and flexible, causing them to flop off the spool and become tangled under the hub, even when the filament is loaded and experiencing tension from the extruder. This holder allows you to position the spool flat against the bottom of the top PrintDry container without relying on the standard "lazy-susan"-style hub. The nub at the base of the model fits snugly into the central hole of the metal liner. The STL files were generated by an OpenSCAD script. The narrower design should accommodate spools with a 52mm hub inner diameter, while the larger version will fit spools with an I.D. ranging from 56 to 58mm.
