Big Phone Holder for Computer Monitor

I have a big phone (Lumia 950 XL) in even bigger protective cover. So I need a big phone holder.

This one attaches to a flat backside of my Dell monitor, when turned to portrait mode. I used a strong double stick tape. You might want to modify the flat part extending to the right to fit the monitor or other attachment point you are using.

There are two version, one for "naked" 950XL and one for phone with cover.

In one of the pictures you can see the holder together with the [headphones
