How to generate a worm drive CAD file?

Hello everyone, I am doing a project for a worm drive for my mechanical engineering class and im trying to find a quick way to generate this CAD file. Problem is I need to be able to set every parameter as I made all the calculations on paper. I am trying to do this at inventor 2019 but I can only set a few parameters and it calculates the rest but i need this cad file to have the exact dimensions that i got on paper. Any advice?
