This Steampunk Mechanical Cheetah by Mechanical Cheetah, Cool.
“The cheetah measures 24″ high and 50” nose to tail and weighs about 40 pounds. She took about 60 hours, spaced over 10 weeks time, to build. She’s constructed out of the usual electrical conduit, transmission parts, and 20-gauge steel.
The cheetahs are part of the underworld ecosystem in the “Timmy” universe. They are couriers of small objects (a sort of steampunk FedEx) and also run in the treadmills. “
