The logic displays are composed of three parts, the PCB, a bevel that goes around the LEDs and a clear plastic window.
To attach the parts to the resin part I used pieces of threaded rod (actually cut off screws) that I glued into the resin part.
I used two-part epoxy to glue in the screws. To keep them aligned while drying I put them through a piece of wood with the same holes drilled in it and then put the PCB on top to assure the alignment was correct.
I needed some spacers between the bezel and the PCB, but couldn't easily find something the correct size. Instead a got a styrene tube and cut off pieces of the appropriate length to make the spacers.
