20T Module 2 Miter Gear 5 mm Bore
A 20-tooth module 2 miter (1:1 bevel) gear, 44 mm across the teeth and 26 mm tall. It has a 5.3 mm slip bore for a 5 mm motor shaft and an M3 set screw with a captured hex nut. Print two and mount them with their apexes meeting, each shaft axis 40 mm above the other gear's hub base, to get a 90° turn for a NEMA 17, a crank or a pan drive. The 45° back cone matches the gear's geometry and also lets it print without supports.
