You can also try and design a model yourself using https://www.heroforge.com/
It's not as free as if you use a proper design programm and create a model from scratch, but it's easy to use and works fine for tabletop miniatures and the like.
At the end you can either download the 3D print file or order whatever you designed (cost depend on what you choose). Never used the files so I can't tell you anything about their quality, but the models I ordered where always quite good.
