Even the more complex and powerful program, Fusion 360 is free for hobbyists. I'm a fan of OpenSCAD, a text based 3D modeling program.

You'd measure the male portion of the part, create it and use that creation to subtract (boolean difference) from the female portion.

An aspect of your mold-making project would be if the mold can tolerate the material to be used. Metal casting is done with various filaments. Silicone molding is reasonably easy with 3D printed molds. What materials are you considering to cast?
the end product would be cast with carbon fiber. ill take some measurements and post them up.
