Drawing Tablet Stand - Over Keyboard

This is a drawing tablet stand that sits over your keyboard. I designed it so that when you are drawing you can easily reach your keyboard. When I started using my drawing tablet I found it frustrating to have to reach for my keyboard every time, and it slowed down the creative process a lot. My desk isn't very large, so I began working on a solution that would let me draw and use my keyboard as compactly and easily as possible. The result is this stand that is large enough to fit a keyboard under it, and you can also choose the desired inclination. I was thinking of making it parametric, but I still don't know how to do that.
