Large laptop stand (15")

I first printed the Laptop Stand by JannesV (https://www.thingiverse.com/thing:2458297) but the base was too small for my father's computer: it was rotating and eventually falling from the stand. So I redesigned it with a bigger base and a guard (~2cm) to prevent it from rotating while using as much space as I could with my Prusa MK2s.

After being assembled with some glue, it now works like a charm.
