Instead of one large part taking 18hrs. This is a 3 part system that will mount all the different boards except the Duet. The Duet will be mounted where the RAMBo currently lives. This is based on 3Dprints design but modified. Mounts directly where the old RAMBo lcd control panel mounts. I will also post a 7" LCD touchscreen mount plate for it soon.

Screw the parts together. Use a rotary tool to add holes and ports you wish.
