Corner Cable Bracket w Holes Single Height

Remix of original: https://www.printables.com/model/59665-parametric-corner-cable-holder-90degrees

Neatly organize and protect cables turning corners at 90 degrees. My edits:

• reduce the height down to one cable height to save material and time, and
• Add mounting holes so that it can be mounted using #8 wood screws either in plane to the wall, or in a corner. The holes have a conical shape to allow flush seating.

This is my first production file, forgive me, it's a bit crude. You'll note that at 0.10mm there is a small blip where the print head jumps across the piece. This is easily discarded. Optionally use 0.07mm resolution and it will be fine, however print time doubles to 5 hours. I haven't tried it at less resolution yet.
