Here's my favorite yarn bowl I've made! It's roughly based on my favorite creature from the black lagoon. I print it with supports only on the plate to minimize any sanding I have to do - you'll want to gently sand the parts where the supports attach so that your yarn doesn't snag! I have provided the STL as well as a 3mf file with painted eyes for Bambu users. I recommend printing this with at least a 20% infill so that it has enough heft to it to hold your yarn without moving around a lot.
This file is for personal use unless subscribed to my commercial plan, thank you!
