The bowl is sort of triangular so I pulled the back out to make it more oval. The westers47 remix was widened on the bed and printed (silver) and then deformed in blender to open the bowl cavity (white). I also pushed up the pallet because I wanted it to be less flat on the bottom. There is a slight lift to part of the flat bottom but it's not significant enough for me to mind, but it currently prints with a triangle of support in a thin layer (see bottom pic) making the bottom not uniform. These are ABS printed at 0.20mm.
