This is the logo of Commodore, which can be illuminated with two 5mm LEDs. It consists of two parts. The face plate is designed to the official specifications of the Commodore logo. The illuminated body is printed from transparent PLA with 100% infill (that is important). It is slightly smaller and will fit through the cut outs of the face plate. The illumination is accomplished with two LEDs (and of course the current limiting resistors).

The reflector can be printed with a layer heigh of 0.4mm with white PLA. It adds quite a bit of brightness and serves as a stand off for a printed circuit board (with the LEDs and resistors). An aluminum foil between the transparent part and the reflector improves the performance a bit, too.

The PCB can be found on github: https://github.com/svenpetersen1965/Illuminated-Commmodore-logo
