Ultra realistic mayfly nymph to be used as a lure for fishing. You can print it in hard plastic and then make a mold from it for soft plastic baits or you can 3D print it in soft plastic and use it as a fishing lure. I originally designed this to be used for fly fisherman in 12mm, 25mm and 35mm but for 3D printing the 25mm and 35mm (1inch & 1.35inch) was the best option. This model is the 35mm which is 1.35 inches. Happy fishing!
