For the past year I have been helping a small company, Raging Mammoth, design its flagship product called The Beer Tusk. Here is a link to their KickStarter video:
They had an idea that looked good on paper, but wasn’t being manufactured efficiently and wasn’t meeting the specifications the company originally had in mind. I contacted them and we worked out a deal to redesign and change the method of manufacturing, from CNCing every piece to extruding them by the thousands. The tusk is now much cheaper to build and opens beers much more easily than the first version.
