Z Axis Motor Mount for Creality CR-10 - Corrected for Glass holder Y Axis travel

This is a slight adjustment to the Z Axis motor mount I needed after installing the "Creality CR-10 Wire management, Strain relief and Glass holder" https://www.thingiverse.com/thing:2328449 which I found impacted the corner of the motoer mount, precluding full and unobstructed Y Axis travel. The solution is to draw in the corners of the Z Axis motor mount to avoid the problem.
