D-Bot Large Foot

I flipped the Z-Motor Mount brackets upside down, removed the front corner brackets, ordered large lead screws and cut the vertical rails of the D-Bot larger to maximize the overall printable height without adding cost. The bed moves completely to the bottom rails with this change.

These feet allow the Z-Motors to not touch the ground. Each foot uses (4) 5x12mm bolts and (1) of the large 5mm bolts (can't remember length right now, its the one used for the spool holder in the standard D-Bot)
