High flow showerhead that has been 3d printer out of corn based plastic. Do not allow continued use of really hot water to run through it. Will fit on any standard 1/2" shower head pipe. Buy this if you want to allow it to swivel (http://www.amazon.com/Opella-205-995-280-Shower-Swivel-Nickel/dp/B0038FLVRK). Use teflon tape for a good seal between the pipe and the head.
