Robo3D Vertical Z Case Corner Spacers

My Robo3d has longer Z rods, and these feet were designed off of the 3d files that Robo3D published to give a bit of vertical height (45mm additional), but still hold the case rigidly.

Slots in the back to hold 1/4-20 screws.

There's a left and a right, two of each make a complete set.
