Hi this is one of the cool gadgets I designed over Sunday, Geared phone holder, you can adjust the tilt of your phone.

Update: Included two new holder variants for landscape phone position. Base without CT letters and a Base v2 version with tighter tolerances.
Base v1 Lose version has additional 0.1mm clearance for easier fit. The bigger gap allows sliding the pieces together more easier.

The models I printed with the following settings:
Nozzle: 0.4mm
Layer: 0.5mm width / 0.25mm height
4 top & bottom layers
2 walls, 10% infill.

Hint: The two pieces are sliding together from the side.

Enjoy!

You don't have to, but if you insist a small donation will be greatly appreciated and help me design & share more open source projects.

Thank you!
