In the last wearable keyboard build, I used thin wood on the bottom, but since I did not have any complex cutting pattern, I realized I could have used a piece of polycarbonate. I will not repeat that mistake, so I designed a simple jig that would help me place holes connecting my 20x20 extruded aluminum keel to a plastic sheet.
I saw a project where someone wanted their addressable LEDs to look like an oversized 7-segment display. To get uniform brightness in each section, they recessed the lights and made "channels" to prevent light from bleeding over.
Projected LED holder and hole jig
The jigs came out perfectly. I added a short cutting section at the tip of the arrow, so if I sand the bottom to expose the light-colored wood, I will have a neat line that I can position on a ruler. I used a small hole instead of the M3 or M4 so I could use a small bit to drill a pilot hole.
Drilling jig
I cut two sets of light channels to use with 8-position addressable light bars, and they fit wonderfully. I put some diffusing plastic, a scrap of plastic from a milk bottle, under the top layer and tested different depths. In the shallow tests, the lights were intense, and it was easy to see the round reflector shape, but when I added as many as eight spacers, the light was uniform across the square and less intense.
Different depths
