I created this as a participation award for my son's high school Esports team.
The profile I provided for this model is interesting because it not only uses Bambu Studio's paint capability, but also uses a “cube modifier” to selectively switch filament colors in the plaque. Simply painting the recessed surface of the text and Splatoon logo didn't produce good results, so I instead created a cube modifier and shaped it to just cover the 2-3 layers at the bottom of the text and logo.
With the painted surfaces, this model takes 9 hours to print at .24 mm layer height. It's much faster to print if you remove the paint and print it in a single color, and it still looks really good.
The plaque I provided is for my son's high school. You will want to customize the text on the plaque using the Customize feature.
