I've always thought a monster that pretends to be a loot chest is an awesome idea so I decided to design this guy. Be careful orienting it so that there is very little support inside the mouth. I moved infill up to 25% to make it sturdier and printed the one you see in the image at 0.08 with fuzzy skin set to 0.4 thick and 0.05 distance. I'm including the 2D art that was my inspiration as a color reference if you decide to paint this (I am going to).

This design took about seven hours using multiple manual and AI design phases across DALL-E, Photoshop, TRELLIS, and Fusion. The AI tag makes me pause and reflect because no design anywhere in Thingiverse is untouched by AI. Photoshop is loaded with it. Fusion is loaded with it. Blender is loaded with it. That doesn't mean the human element isn't the guiding force behind why the art is enjoyed.
