I modified the sizes to be 16mm and 26mm (the kids laptops vary wildly in width). I kept all your present settings, but I changed the length of the overall object to 75% (while keeping everything else at 100%).
This allowed me to easily print with NO supports, and I only had to snip off a really tiny portion of imperfection near the top. Well worth the speed up in time I got from that.
Thanks for making this!
