Just a lightbox I created for Auburn, used just slightly less than 1m of leds to go around. The back has an extended lip to allow for the mounting of the leds, I personally find that the double sided tape isn't the best so I use hot glue in various spots around it to secure it. Printed on Bambu X1C with Textured PEI plate, 0.4 nozzle, 0.2 layer and have this postiioned on the plate so that none of the extrude lines interfere.
