Comfortable mug handle mold

I once stumbled upon the research of Joe Thompson via https://www.oldforgecreations.co.uk/blog/mug-handles , discussing how mug handles aren't comfortable at all. I agree and I LOVE elaborate (free) research like this. So in my current pottery wheel throwing class i want to apply his research and test his hypothesis. To do it as accurately as possible I made some 3D printable molds to press the clay into according to the dimensions he describes.

As of now i haven't printed or clayed it yet, so i can't tell you if it's comfortable.
