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.
The author marked this model as their own original creation.
