how to make a brace,orthese around a stl file

i am a casting technician and i look for methodes to make simple a brace, orthese around a bodypart, mostley a hand, arm or ankle.
I now try to learn rinoceros 4.0-5.0 but it is verry complex.
When i have some skills i would like to buy a 3d printer to make the products.
Thanks for any input
