Ultibots D300VS Bottom corner plates

This is step 1 in an enclosure system I'm working on for my D300VS, but even if you don't plan to enclose your printer, they add a nice aesthetic finish to the bottom. Print 2 of the "y-z" plates, and one of the 'x' plates, which has an opening for the wiring mast in the X corner.
There's about a 1cm air gap between the plate and the bottom of the bed.
The plates are held in place via tight friction fit on the motor mounts.
