Level Wind (Diamond Screw)Saw this the other day on a filament respooler model and HAD to model it up and try to print one; such a cool concept. The level wind (diamond screw) allows you to rotate a rod in a single direction, yet the carrier will automatically move left and right. No need to reverse the motor. The pawl (round disc) interfaces with the track and "turns" at the each end realigning to follow the return path.I've included the Fusion 360 source file so you can step through how I made it.Print Settings0.12mm layer height, 0.4mm nozzel, 2 walls, PETGExtra Bits2 M3x8 (ish) bolts2 608 bearingsMaybe a bit of glue if you're so inclined, but I didn't need it.
