Whats is Nylon?   Nylon is a 3D printed plastic and it is Acetone Proof. The Nylon plastic has a higher tensile strength with some flexibility and you can be rougher with it. You can soak in acetone for days with out the plastic becoming weak. This tool can last a long time if you clean it after every use.
