Remix of a simple (vertical) stand to fit for thicker tablets (with cover). Max width 1.8 cm.
(the original had 1.1 cm, so take that if it fits better for you.)
It should fit to surface (pro) 9,10,11 with a cover without lid or keyboard attached.

I know, not the biggest change, but maybe someone don't like to tinker on .stls so here is an extra version of it. ( and just ask if you need a wider/smaller version)

It's a gift for my father, so I just used the empty case for measurement and photos.
