NinjaCookie Bottomless lower brackets

I wanted to install Dual Z rods using Ninjacookies brackets, however My printer is flat against the surface with center brackets bolting it in place, so raising it wasn't something I was interested in.

Remixed the lower brackets to remove the base under the extrusion, then lowered the 4 holes that bolt into the horizontal extrusion by the same amount (4.5mm) so they would line up in the new configuration.
