Materials and tools:
- glue gun
- aluminum tape
- led strip (here is the one I use): simple 1m white led USB

- soldering iron (optional)

RECOMMENDATIONS

- use a textured PEI sheet
- use the print profile, it has quite a few setting changes that help achieve the best results
- make a hole for the USB strip wherever you like it best with the soldering iron or in the slicer

- use the aluminum tape on the inside of the backplate to help with light diffusion
- glue the LED's the further away from the colored design possible; placing them too close ruins the diffusion and the individual LED's become visible

Bambu Studio Settings:
I always recommend using the print profile I provided since it has settings with which I've been able to get the best results.
If you choose not to here are the main slicer settings I recommend:
- preferences (ctrl + P) → activate developer settings → Quality →Advanced → First Layer Flow Ratio: 1.04
- Quality → Wall generator → Arachne
- Quality → Wall transitioning threshold angle → 50º
- Strength → Advanced → Infill/wall overlap → 20%
