I modified the gripping smartphone holder so that it can be used on a Ford Fiesta (MK7) with a CD Drive. Please print it in PETG or ABS, as PLA might melt in the summer.
add rubber bands on the arms of the smartphone holder to increase the adhesion.
If you want to rotate the Base, you can use "FoFi_smartphone_holder_body_180.stl" and the two parts that were already included.
The base was modified using tinkercad,
feel free to modify it.
