Phone stand that uses a rectangle piece to set the angle. 

The three angles can be seen in the pictures.

How to print

Print main part with large brim (e.g. 6mm), no support.
Print the decoration strips twice and insert them.

The picture shows you 100% size. It can hold a tablet, but at 150% or so, it's obviously more sturdy.

How to use

Insert the rectangle in the backside of the main part to set the angle.
Insert it from the top (see last picture) to store it, or carry it in your pocket, etc.

Origin story

When I was ready with my other adjustable phone stand there were a couple of things I wanted to improve. This design is better looking, easier to use, prints quicker and is more stable. 

Potential updates

I'm thinking about adding a icon insert on the flat part, like a ★, ♥ or ♪, should I do that? Or is that something you would do yourself in the slicer?
