Seahawks lightbox, tried to get the gray markings down the middle too work but invested too much time and couldn't.
Scrapped the model and just redid it without them.
Original example printed with Bambu basic PLA black, white, blue, (bambu) green, and Kingroon gray PLA.
As always be sure to heat up your hotend to clean any old filament that is stuck to the nozzle before sending the print. This will help keep color wisps to a minimum.
The back has a negative cube included in the objects that you can move and scale as you need for your LED installation.
Enjoy and Happy Printing!
