This is a quick remix of Bambu Labs Hotend LED Coloured Insert from mobiobi.
The original model was 2mm thick so it didn't work well for non-transparent filaments. I shortened the depth of the front face to 0.5mm and added walls so the light inside the hotend is colored as well. The “height” of this insert was also changed from 5.47mm to 5.65mm to provide a tighter fit.
Additionally I've included a Bambu Studio 3MF file for single and dual color prints that is setup for transparent prints as outlined in this post.
