3D models of 20D mm gearmotors (3MB zip)
This file contains 3D models (in the step file format) of the 20D mm gearmotors. Note: these models only accurately represent our newer versions with 18mm-long output shafts; they are not accurate representations of the older versions with shorter output shafts (i.e. gear ratios 29:1, 56:1, 73:1, and 154:1).
