I designed this model to be used as a mug, so mine is clear coated in foodsafe epoxy resin. I used Alumilite Clearcast from Amazon. It's fairly cheap, FDA approved and looks great. The model that's uploaded also has the octopus arms as separate parts of the same object, so you can select them for coloring.

Print Settings:

• Adaptive Layers (I hit smooth a ton of times so the transitions wouldn't be so visible)
• 4 Walls and 25% Gyroid Infill gave me a pretty solid cup
• (OPTIONAL) Fuzzy Skin with a point distance of 0.2mm and a skin thickness of 0.07mm with contour only selected in Bambu Studio. I'm not sure about other slicers. This hid the layer lines, but it also kind of hides the texture on the octopus arms. It's up to you, but I went for the ceramic look.
