Convert Drawing to 3D Prototype Model

I have a photo (see attachment) of a mechanical part that I want to turn into a printable prototype. The photo shows overall dimensions and the key features, but it is still quite rough, so the first step is translating it into a clean, moderately detailed 3D model...
