I designed this light box ON AIR because I wanted to be able to turn this sign on/off when I am working (from home) to indicate that I cannot be disturbed.
I used standard black PLA for the box, and opaque red PLA for the plate and natural transparent PLA for the letters.
For the light, I ordered a small self-adhesive LED strip, USB, on Amazon: https://www.amazon.fr/dp/B0BYNM7TZW?psc=1&ref=ppx_yo2ov_dt_b_product_details
If you didn't find it, just look for a 1 meter long LED band working with USB.
The hole on the back allows a standard USB plug to come out normally.
I placed the plate upside down for printing because on a textured printing plate like on the Bambulab, it creates a very clean, very industrial design.
If you do not want to print it upside down, I advise you to check the smoothing of the upper layers for a smoother result.
Furthermore, very low infill allows light to pass through the opaque PLA (here in red).
