I needed a lower profile stand from the original to fit inside a desk drawer but still allow ample venting for my laptop when the lid is closed.
I have two versions: 20mm and 25mm, which is the size of the outer diameter of the lower circular stand portion. Both are the same height (40mm tall) but depending on how close the keyboard is to the edge of laptop shorter heights may be needed.
Much like the original, there are cutouts at the base to not block air flow and the stands also fit together to help with portability.
