Fits snuggly into 250x210x210 build volume of Original Prusa i3 MK3 in one piece. Alternatively, you can print three separate pieces and glue them tog...ether.
Single piece needs supports, overhang angle 30°and support from build plate only is enough.
Separate pieces could benefit from brim.
Rescale as you wish.
You can use cheap shades for the goggles and cut them to fit.
