Four color Colts lightbox. Looks great lit up. The gray I used in this print is the first one I found that lets the light come through and not look brown. It is kingroon gray pla. The other colors are bambu basic white, black and blue. As usual with the lightboxes we make the white prints first so be sure to heat up your nozzle and clean any old filament off it before sending the file to the printer. This helps keep the wisps to a minimum. The back has a negative cube that you can move and scale to your needs for the light install. Enjoy and Happy Printing!
