Scientist and 3D printing enthusiast Rémy Vicarini created this 3D printed mini Iron Man helmet (or is it Iron Cat helmet?) for his cat Cathode.
And best of all, just like in the movies, Vicarini's Iron Man helmet has a visor that can move up and down to open and close, respectively.
If you'd like to 3D print your own cat helmet, Vicarini shared the STL file over at his GrabCAD Community page.
