New open beam component based on OpenBeamUSA's L bracket.
Basically I wanted a one-piece corner unit that mimicked the original design.
The optional foot mounts over the corner hole in the solid face to hive you a 5mm stand off.
(sorry about the print quality, I found the extruder was loose on the carriage after this print).
Print it out with two tops, two bottoms and two perimeters at about 30% fill. Seems to be pretty strong.
