Gear for wade extruder
by shedir, published
this is a new double helical gear 13/72 theeth. the module is 1 and the pitch is Pi*m (3.14mm). pressure angle is 20Â°
doble helix 15Â° inclination. correct axis distance is 42.5mm.
I suggest to print it with a 0.15 nozzle for best results. it fits perfectly and turn softly.
the file is a rhino file (77Mb) so you can edit it, and export in stl resolution like you wish. you can also modify it like you want. just don't change the teeth profile, because they are involute teeth.
