Print base face down with supports touching build plate. You can get away with not printing supports in the base part but you might see a little drooping but mine was fine without it. Otherwise print supports everywhere after 65 degrees to be sure.

Pieces will need to be super glued together. 3 total pieces, the base is one piece, the front white/red insert, and the back cover.
