Phone Stand remix

Model updated to make the front feet to be more stable.

This is a remix of Phone stand / Tablet stand by protywu on Thingiverse: https://www.thingiverse.com/thing:4705428

I wanted a taller version with room at the bottom for my charger cable and also slightly narrower to suit my Vivo phone.

UPDATE: There were a couple of small errors in the model so I uploaded a fixed version and removed the original.
