I made a wall lamp of the double r sign from twin peaks.
I used a regular battery operated fairie light for the "Cafe" part of the sign, the "neon" light is battery operated E-wire.

Is is divided into parts that would fit 200x200 print surface. If you decide to make a smaller version you will need to make the holes for the wire bigger. It is quite tricky to put the e-wires in, I used a 3D pen to keep the wire in place while wireing.
I printed mine in silver PLA filament, exept for the "cafe" part, I used transparent PLA for that, and then painted it with yellow sharpie and acryl paint.
