Since Quadlock doesn't make a case (probably for good reason, its fragile phone that shouldn't be strapped to a bike) here's an adapter to put your fold on the dash of your car.

Don't recommend using it in vibration heavy environments but it works well in a car.

Its currently a crude (but fully functional) Frankenstein on two existing designs but I'm working on making changes for ergonomics and structure I will post a v2 in a couple days.

Its got some funky overhangs on the quadlock that will be borderline impossible to print with FDM but please let me know if you manage.
