Steelers lightbox
Original example printed with Bambu basic PLA black, white, red, blue, yellow and Kingroon gray PLA.
In current form it is a six-color print but if you only have one AMS you could change the logo to all black and white with the paint tool to drop it down to a four-color print with just black, white, gray and yellow. It would still look great that way.
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!
