Erius was inspired from all the RPG games I've played in the past. As for his design I would say he's part Link (Zelda), Mickey Mouse, and a cute elf.
The model was sculpted in ZBrush. It stands roughly 3.5 inches high (8.3 cm). I didn't hollow him out so it's a very sturdy model.
I do have a painted version that was printed out for myself but unfortunately that is not available. That process requires a texture and special material. Feel free to paint him yourself!
