Sealphin

thingiverse

This Sealphin was inspired by the Ambiguous Cylinder illusion of Kokichi Sugihara. It's actually a seal that's masquerading as a dolphin in its reflection. Print Settings: Better to print it at a fine resolution of 0.1 or 0.05 for best results. If speed is your priority, try printing solid walls with 0.2mm thickness but use 0.05mm for the top layer.
