Thwomp not only guards Bowser's dungeons... he also has a side gig guarding my keys! Not a very lucrative career, I'm afraid, since all he gets out of the deal is pocket lint and all the Chap-Stick he can use.

I made mine out of one shade of gray PLA, then darkened portions with acrylic paint, white PLA for the eyes and teeth, and a thin coat of Liquitex Gloss Medium & Varnish to give it a nice shiny lacquer.

That being said, if you happen to have multiple shades of gray filament, I have included STL's for both, as well as an STL for the grays printed all-in-one.

No supports needed, infill around 30%.
