Minimalist top glass riser with added ventilation slots and TPU Light Shield, which will support 8 or 10 mm LED's.
For P1 series USB port only use a 5V LED and do not excess the 1.5A of the port, i used and cutted a LED strip like this one:
For full enclosure is better to print it in petg, abs or asa.
Personally used PETG for the structure and TPU for the light shield with the following variation to the standard 0.2 setting in Bambu Studio to apply only for the structure:
Infill: 10%
Support: No supports
Brim: manual, 10mm
