Mini Mill X2 Z Axis CNC Conversion

This is a CNC conversion for my Little Machine Shop mini mill (3990).
I got the bulk of the design from LittleCareBear's design, but I wanted to make some changes.

Parts needed:
M5x0.80 20mm bolt (7)
M4x0.7 20mm bolt (4)
M4x0.7 nut (4)
M5x0.8 18mm flat head bolt (4)
M3x0.5 20mm bolt (4)
M3x0.5 nut (4)
608-ZZ 8x22x7 Bearing (2)
8x32mm shaft
8mm Flange shaft coupler (2)
20T GT2 pulley

M5x0.8 nut (4) - There are pockets in the back of the mounting bracket to hold these.
