I made this light box based on the ON AIR one I have made because in fact, with the same box, I just had to design a new plate ;)
I used standard black PLA for the box, and opaque orange 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 orange).
