64x32 M3 LED Matrix holder

thingiverse

This is a simple rectilinear box that holds an M3 64x32 LED Matrix display. The displays I buy come with little T-shaped magnets that screw on the back. I put four of those on in the corners and on the 3d print I superglue washers on the stand-offs I have incorporated into the box. The magnets grab those, and you can use a screwdriver or thin rod to decouple them later (That's the hole in one of the stand-offs.) The other holes are for power jack and the other hole is for a small pushbutton reset switch for the project. I mount the microcontroller for the project directly on the back of the display board. The display is recessed about a millimeter from the bezel. That allows a diffuser to be mounted over the display. Nothing fancy, but it works.
