I previously built a Roubo phone stand that gets used all the time. But phonestands are so useful that I have more.
A lot more.

I designed this one in OpenSCAD, a free text-based CAD program, and it is fully parametric. You can adjust the size and the angles to ridiculous degrees. But this is the one that I like and use. I think I have 4 of these around the house and I’m still tempted to print another.
They’re great for video calls, or just having your phone visible but not in your pocket.
Here’s the scad: phone-stand
And this is the stl of the one that I use all the time: phone-stand-stabilized
I hope you give it a print and enjoy.
