"I Gotta Fever, and the only prescription is MORE COWBELL!" One of the most awesome and favorite percussion in the universe. I can never get enough cowbell. Thought about this at the end of last year and I can't believe it still doesn't exist. Playing instruction and printing, etc are here : http://www.youtube.com/watch?v=2zECI5dZEsQPrinted with 100% infill, it took me 8-9 hours of very high speed(150mm/s infill) in 125% scale. This thing is LOUD, so play accordingly.
