The front plate is 2mm thick PVC. After some thoughts, I don't think it is the best material for this application. Teflon or other higher quality plastics would be much better as PVC starts becoming soft at 60°C (I think the star PCBs can get pretty close to this value) and it becomes a bit yellowish over time because of light radiation.
Holes are drilled at 8mm and then enlarged with a 90 deg cone end mill to about 12mm. The plate is tighten and "rests" on the solder of the wires that connect each star to its neighbor.
On the production panel I will use teflon, drill everything with a CNC mill and holes will be matching the LEDs perfectly, watertight without supplemental front screen so no light losses. I might as well offer a "DIY kit" with LEDs mounted on stars (done in a real reflow oven of course) at killer price, a good driver and a heatsink. I do believe most companies that sell star mounted LEDs are exaggerating their prices and sell much higher than what it actually costs them.
