Alternate Spool-Holder for PrintDry

thingiverse

This is an alternate spool holder for the PrintDry. I tend to dry and feed filament out of my PrintDry at the same time. Flexible materials like NinjaFlex and PVA are so soft and flexible they tend to just flop off the spool and get wound around underneath the hub and get caught up in a knot, even when the filament is loaded and under tension from the extruder. This hub lets you place the spool flat against the bottom of the top PrintDry container without the stock "lazy-susan"-style hub. The nub at the bottom of the model is sized to fit into the center hole of the metal liner. The STLs were generated by the OpenSCAD script. The more narrow one should fit spools with a hub inner diameter of 52mm and the larger one will fit spools with an I.D. of 56-58mm.
