Remix of Laazurus' Migbot Extruder Brace w/chain anchor

The way, my step motor is placed inside the extruder mount forced me to put a gap to the extruder brace.

Rotating the motor was no options. The other three sides had no space for the cable plug.

So I took the "b" variant and added a spacer for the plug.

Hopefully tomorrow I will apply the cable chain to the extruder and than I will provide a photo of this one.
