Use PLA, then if you don't like it it will biodegrade. Also that's the plastic used to test print. Expect to use around 100 meters of 1.75mm or so. Designed to be printed at 0.32mm layers with 200% line width. Other options may work fine, that's just the intended detail level. My print was single line shell, 2 layer top, 2 layer bottom, and 20% rectilinear infill. Body took about 5 hours, base 4, top 3, disk 1. So expect to spend some time on this. Really should not need support to print this. My test printer has mediocre cooling and barely acceptable bridging and only produced minimal bridge issues and only at the top of the doorway of the base. The flaws were easy to trim away.
