Because everybody needs a hobby and why not one that includes your pets, cat owner Rémy Vicarini 3D prints various helmets for his feline friend Cathode. This is a LEGO knight helmet and motorcycle helmet here, but below are videos of Rémy making a functional Iron Man helmet, bicycle helmet, and astronaut helmet for Cathode as well. What a well-helmeted cutie! So, how many more lives do you think these helmets add to a cat’s existing nine? My guess is at another three or four, easy.
