It's a doorstop, that looks like cheese. Print in TPU at somewhere around 5-15% infill. Depends on the style of infill and the TPU you use, so try a few to see what's best for you. Yellow seems obvious, maybe orange if you're American :) Use PLA if you want to use it as a prop or an ornament, maybe pop it onto a cheeseboard as a decoy, the possibilities are limited!

I'd suggest using ‘avoid crossing perimeters’ or similar setting, depending on your slicer, to avoid stringing over holes. It'll change your life when using TPU. Ask me how I know.
