I printed this Art Palette and Cover on my i3Mk3S in PETG for my sister's birthday (she's a nurse and likes to paint). I sprayed some Rust-Oleum 280882 Specialty Tub & Tile Spray Paint (12 oz, White) on the top to simulate porcelain where the oil paint would sit. It is similar to acrylic epoxy. I forgot to take photos and save the 3mf files. So, I have uploaded the STL files, and you can probably use the standard Prusa settings for PETG (or other material). I also included an image of my SolidWorks 3D design file for reference. The parts printed well.
