I have modified the design of this 3d printer head robot flange on the original design that I designed earlier https://www.printables.com/model/154117-extruder-arm-robot-flange to fit a scara robot arm designed by #HOW_TO_MECHATRONIC.
You can find the design of the scara robot here:

The author remixed this model.
