LED matrix display corner wall mount

Designed as a version 1 for standed 64x32 pixel LED matrix display.
Corner holes are for screws within the matrix itself, the display board acting as a connect for the two pieces.
This design expects +/-2 mm panel width gap to accomodate for printer's elephant footing, manufactoring tolerances, and screw hole misalignment.
Any Arduino or Raspberry boards can be bolt and nut or zip-tied mounted on the rear.
Corners are designed for 3M poll tab tape or through the use of a lighter on a metal thumbtack to melt two grooves for pin mount.
Large vent holes for mounting boards or if you use any full Raspberry Pi baords for cooling and airflow.
