A mount for TETRIX style Motor/Servo controllers. It allows access to all important sides of the controller, and for the controller to slide out for easy access to screw terminals, encoders, and plugs. Its meant to use #6 nuts and bolts to fasten the individual controller mounts together (since it is modular) and it attaches to 1" t-slot aluminum extrusion from McMaster Carr with 1/4" bolts.
