Step 6Glue in the LEDs
For optimal light transfer, the LEDs must be glued in the notches. Any glue that dries optically clear will do - Krazy Glue, many epoxies, or acrylic solvent cement.
To start, lay a piece of clear scotch tape or packing tape on one side of the sheet, along the edges with LED notches.
Inside of each notch, stick in an LED so that it is pushed as tightly into the notch as possible. Be sure to observe polarity - each LED should be placed the same. Put a glob of glue on each LED and let it spread into the gaps. Once all the LEDs are glued, lay another piece of packing tape on top of the LEDs and push on each one lightly, so that the glue squeezes further between the gaps.
Do all 28 LEDs on the bottom panel, and all 14 on the middle panel. Again, observe polarity, and make sure you put the right colour in the right place. Once the glue is dry you may peel off the tape.
