About this 3D model

Here is a printed prop that I designed with a key way so that the pieces slot together easily. Its rough looking but its printable and it works! Due to printing the prop side ways, It has high tensile strength. Although I wouldn't use these props on an expensive easy to break plane! You'll find out very quickly whether or not your print is going to hold or not. Roughly 1 out of 6 of mine exploded,or sheared on take off. But if it can handle take off then your pretty safe to fly!
