I added stepper motors to my github repository of 3D models of Openbuilds parts: GitHub - matthew-yates/openbuildsParts: Parametric models of Openbuilds parts The file "motors.scad" provides two OpenSCAD functions named "nema17" and "nema23" that can be used to produce models of the three types of stepper motors that Openbuilds sells If you save the file "motors.scad" in the same working directory used for modeling, the following example code: <CODE> include <motors.scad> translate([210,0,0]) rotate([90,0,0]) nema17(); translate([100,0,0]) rotate([90,0,0]) nema23(); translate([0,30,0]) rotate([90,0,0]) nema23(type="ht"); </CODE> produces the models shown in the image linked below. openbuildsParts/images/motors.png at main · matthew-yates/openbuildsParts
