Motivated by the need for an interval timer at the gym with a display large enough to be seen by an entire class.  Combines 2 large 5mm pitch 64x32 pixel RGB displays with a couple of Adafruit Featherboards to control the IR remote and display logic.  Operated by an A1156 Apple remote control.  Similar in approach to the Adafruit slot machine, but entirely original 3D parts and coding.

Display design kept simple for readability but also looks similar to an 80's digital watch.  Still a work in progress.

Chemcast Black LED Acrylic sheet from TAP Plastics covers the LEDs and creates a pleasant diffusion.  Link to product here: https://www.tapplastics.com/product/plastics/cut_to_size_plastic/black_led_sheet/668

Multiple side modules needed to join and cover full length of combined matrices.  Also contains slot to hold plexiglass.  Holes aligned with mounting screw holes.  M3 (8mm length) and M4 (12mm and 14mm length) socket screws, washers, and nuts needed to join modules.  You can choose between the side modules with or without hanging brackets.  They can be placed at the side or top to mount the display any way you please.

Corner pieces are similar in that I included designs with holes for the AC cord to be fed through and connected to the power supply.  I don't currently have an image of it hooked up this way, but will add it shortly.  

Power Supply mount is matched to an 8A 5V PHEVOS power supply available from Amazon:

For both corner and sides, I used PrusaSlicer to create the honeycomb fill.  Most pieces do not require supports except for bracket which was limited as much as possible.
