Made for the Printrbot Simple with the XL upgrade, but can be easily modified to fit any Printrbot. A nice way to organize a few switches and status Leds. I have also included a second version of the mount with two mounting points to mount it vertically on the front/side of the Printrbot tower. (switch_panel_mount_version_2.stl) Designed to fit four 12mm flip switches and five 3mm leds w/ holders [6mm together] This panel sits on the side of the printrbot and is held in place in the notch between the body and the tower back.
