Phone Stand

The print is very simple.

To connect the two parts together, I used a 15 mm x 15 mm x 1 mm aluminum profile with 65 mm in length, but you can use any length, that fits your device.
It should be possible to use phones with up to 160 mm in height.

The pockets have a 1 mm grove, that is 8 mm in depth and have a general depth of 5 mm. Keep that in mind if you use a solid body to connect the parts.

I added the freecad files for easy remixing.
