A box for mounting on the Mendel90 printer to house switches for accessories. I mounted a perfboard in mine with mosfets and switches in parallel. That way I can switch accessories within gcode or manually. The switch openings were designed to fit these switches https://www.sparkfun.com/products/10727. The bolt holes align with the ribbon cable clamp bolts in the Mendel90 Dibond so that all you need to do is replace them with longer bolts to mount the box.
