Phone stand with variable tilt

Tilt-adjustable mobile stand.
Tap gasket should be used as shown in the attached picture.
If the movement is not smooth, an adhesive tape is placed over the gasket.
To prevent the mobile from slipping, a line of silicone can be placed.
To prevent the holder from slipping, silicone dots can be placed on the foot.
In printing dynamic quality is used.
The support must be used in the part p1.
Parts p3 and p4 are not identical. Do not print one twice.
The gasket should be printed with flexible plastic TPU (I did not try that I used a ready-made tap gasket).
In order to assemble you may need to abrade the overlapping surfaces.
Also if you find any thing wrong with this please let me know so i can work on it. Thanks!
