Go to Thingaverse for more information on how to 3D print this generator. The page indicates it was made with a 15x5x5mm magnet which we don't have. However, the designers at Akinora told us this larger block magnet will work very well. Smaller ones such as the 10x5x5mm & 12.5x5x5mm will also work.
