I have added an enclosure to the electronics (printrboard, gshield, and PSU) cut out of MDF with a frame of aluminum extrusions. The front panel will be added soon to include quick connectors for the motors and limit switches as well as a power/kill switch.

Also, a dust collection tube has been added. This is not an ideal design, since it is hot glued and zip-tied, but when I upgrade the spindle I will design in a full dust collection system. This just makes clean up much faster.
