SmartMatrix Picture Frame Bracket

thingiverse

I designed a solid plastic border that fits perfectly around my SmartMatrix 32x32 LED display and holds it securely in place within a square picture frame. The border is designed to fit snugly, leaving no gaps between its outside edge and the inside edge of the picture frame, which eliminates any light leakage from the rear. This design becomes especially noticeable when my display is sitting on a window sill with daylight shining brightly behind it. Using OnShape, I created a custom design for the solid plastic border that matches the exact dimensions of my SmartMatrix 32x32 LED display and fits perfectly within the picture frame. The border was slightly too large to print out in one piece on my Prusa i3 MK2's printing bed, so I divided the design into two parts, which I printed separately. Additionally, I have an IR receiver located at the top of the frame for an IR remote control, and I designed the top half of the border with a notch to accommodate the IR receiver's leads.
