Summary

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/jYAFGD5cmCj

I wanted a holder that :

• is active (provides power) without nightly cable hassle waking up the wife
• is easy to aim and slide in, even when drunk (rather thick walls with chamfering on top)
• has some room to get my fingers behind
• has an easily reachable Home button
• has some half decent countersunk mounting holes to screw it down.

The phone fits fits snugly, the connector is a tight fit so it won't slide out.
This Thing works like a charm ! :)
