Parametric NEMA 17 Stepper Motor

thingiverse

The NEMA 17 models I found online didn't quite fit my needs for designing some Ender-3 attachments (searching wasn't as productive as I had hoped), especially since the main one I tried had incorrect mounting screw spacing, so I designed my own. Not intended for printing, but for being a placeholder for designing other parts. You can use the .stl versions, or if you have OpenSCAD, just `use <nema17.scad>` and then call `NEMA17_Stepper();` or something like `NEMA17_Stepper(h = 40, lores = false, colorize = true, show_screws = true, show_jst = true);` Current parameters include: * w - Width for the stepper. 42 is often good. * h - height for the stepper (defaults to 34) * rotation - Angle of rotation for the shaft * lores - faster preview version when set to true (the default) * colorize - show model in colors (defaults to false) * show_screws - shows the screw heads on the bottom (defaults to false) * show_jst = Shows a connector of the JST PH 6 style. Updated hires versions have better bevels, improved rounding on vertical edges and a more accurate JST connector.
