This is model of adjustable phone stand version 2. It can be tilted at a great angle. There are 10 positions with 7,5deg steps. The stand consists of 2 parts - base and C holder. To tilt C holder just press buttons on the base (from both sides). Buttons are inegrated into base design and easily 3D printable. The only element which needs support is the guide slot in C holder (the support block is part of the model) and cutout for charging cable (support block also integrated). The support blocks work for me well and can be easily removed (see video). If you choose not to use the custom support, you can remove it in your preferred slicer and let it to build automatic support. After removing support you may need to clean the upper surfaces (the ones that were supported).
The C holder in this version 2 is with cutout for charging cable. So that connected mobile phone can be easily inserted into holder without having to disconnect the cable.
