The design is easy to print, you do not need any additional tools. You can print everything in one material. I designed it in terms of PETG, printing with ABS the handle will not work because this material has a different level of shrinkage, keep this in mind. You don't need to pull out the airflow control bar, just set it in open mode when the handle is retracted.

To use the holder you have to push it in and out by hand. As you might have noticed the holder is at a slight angle to the dashboard in the car. I added a mechanism that normalizes this relationship, setting the handle straight.
