The tetrapod is a form we've been long enamored with, and was a perfect project to cut our teeth on our CNC mill. Its gratifying for us to see raw chunks of aluminum turn into a shape that beckons to be handled. The process taught us a ton about programming and making sturdy setups and we are really pleased with the finished product. These tetrapods looks great on a desk or around the house and come in a few configurations to suit your needs; simple art object, in-hand stress relief, pen holder, phone stand or whatever else suits you.
