I have lots of different generic motors, and I need them for a couple of projects that involve the Arduino. In order to make the motor less ugly and more capable of being screwed on to something, I made a parametric case, so that I could put in the parameters, and get a case for any of my motors. Then I realized that other people might need a motor case too, so I put it on Thingiverse under public domain. It also comes with 2 example motor case, for the motors shown in the pictures.
(It is not physically tested yet, although it has been theoretically tested)
Now you can change the resolution for better prints and faster rendering!
