About this 3D model

Hello. I tried to design the holder for a universal phone size (fits vertically) or tablet (fits horizontally). I print it from PETG for better flexibility. However, I recommend printing from ASA or ABS due to the temperatures on summer days. I do not recommend it from PLA!!!! although it can also work. Printed on Bambulab X1C layer 0.2. If something is wrong or you have comments, write!!!! I will try to fix it. EDIT: Added hole for charging cable.
