Prusa i3 Z motor mount

I wanted a bit more strength in the Prusa i3 Z motor mount, so I used the original as a reference for the part you see here. Makes use of all 4 m3 motor mounts and an added support arm for increased stability.

Mirror this part to print the right side. I use Netfab or Cura, which are both free apps.

Note that I have printed this part, but have not checked fitment. While I did use the original as a reference, If someone would leave a comment and confirm fitment, that would be great.
