Simple cradle for the optional controller for the 3018 CNC (sold under a bunch of different names). This slides into the aluminum extrusion, and I use a dab of hot glue before sliding it into it's installed position. You can mirror it in your slicer if you want to put it on the other side. The controller just fits in with all buttons still accessible.
