This is a derivative of a Yellow Submarine model by 'seedee' (https://3dwarehouse.sketchup.com/model.html?id=ffa5a9b0c0f629b78b02d321c58ac567), optimized for 3D printing. I used lemon yellow, sunshine yellow, orange, red, pink, blue and brown fine point Sharpies from the "80s Glam" collection to colour the model. I used Netfabb to split the model and plate the halves for easy printing without supports. Sliced in Makerware, 'High' profile. White PLA. I lightly sanded the halves before gluing together (The seam also needs to be filled and sanded before painting the model.)
