If you prefer to manufacture in house, I am currently working on a more student machinist friendly version of the product shown above and I can share the files with you.

No, for something that cheap im sure it wouldn't be a problem to buy. I agree with driving one wheel directly, and wanted to do it, but im not sure on how to go about doing it. Especially with the AM Shifter's without experience.
