YAPS: Stabilized phone bed stand

Yet Another Phone Stand

I like to watch movies or television in bed on my phone, while laying on by back OR on my side. This stand is optimized for that.
It has an enlarged footprint for extra stability in the horizontal orientation. And it can be placed almost vertically to facilitate sideways watching.

This thingy is designed for a Samsung S9, but I assume that you can make it work for other phones too by adapting the scaling in your slicing program.
