Phone Holder

The size fits perfectly for a Galaxy S9 smartphone with this [transparent case](https://www.amazon.de/ESR-Transparent-Ultrad%C3%BCnnen-Unterst%C3%BCtzen-Durchsichtig-Klar/dp/B078PFDSQ9/ref=sr_1_1_sspa?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=galaxy+s9+h%C3%BClle&qid=1556355164&s=gateway&sr=8-1-spons&psc=1). It is small enough such that the smartphone will not jump out even if it gets very shaky.

I recommend cable ties to mount the holder.

You need to scale the print for another casing or smartphone. To give you a hint, currently the inner size is:
- width: 72mm
- depth: 10mm
