This can be printed using anything, but I used PETG at 0.20 layer height and 2 walls. Its pretty simple to print and does not need supports. I also added a “spreader” to the part so that the “big support” is more securely held to the frame and doesn't pop out when using the XTouch.
The author remixed this model.
I remixed part of the “big” support bracket to create this cover to hide the wires.
