most CAD software will let you subtract one shape from another producing a negative that can resemble a mold.  Depending on the geometry you need and the material you intend to use, you will need to make multiple pieces of the mold and alter features for easy removal.

If you already have the STEP file, you can load that file in a CAD program to create the mold yourself. You do need to add an interface to pour or inject the material you want to make the prototype from (also add an overflow opening, depending on the product). I think [this answer](https://3dprinting.stackexchange.com/a/11496/) answers your question.

I need to turn a prototype into a mold. Conventional metal molds are too expensive. I have the STEP files of the prototype. Is there anyone here that does that?
