Thanks for the start, @Velocity_2177! I wanted to flex the PrusaXL and color my first model for 5 colors.
The blue in the model is coded for PETG in the .3mf file as that's what I had on hand.
I scraped the surface of the boot-up screen with the edge of a razor blade to flatten any surface variation. I'm assuming using PLA and PETG would not have that issue. Did not have time but the finishing technique might be helpful.
The author remixed this model.
Mesh is repaired and watertight. Screen depth increased by 2mm and separate screen component generated.
