Lasko 20 inch Wind Machine Fan Knob (flat bottom remix)

prusaprinters

See https://www.printables.com/model/34342-lasko-20-inch-wind-machine-fan-knob for most info.This remix has a flat bottom.  My thinking is that printing with PETG on the textured sheet, the texture on the bottom provides plenty of friction, and this way the force of turning the knob is transmitted via the bottom surface and the infill (vs. perpendicular perimeters), and the infill can end up printing faster than the perimeters for the interior gaps.  Also this way the gaps aren't there to collect silly putty, clay, or whatever else…There's also a deeper version that may be useful if your printer isn't tuned to bridge PETG - the extra depth allows for quite a bit of sag in PETG bridging without running out of space for the bolt-like part of the fan.  The normal-depth model (or original) should be fine if bridging is tuned.If you like this, please rate the original.
