This adapter allows you to use a quadlock base with a magsafe charger.
I am using this to mount my iPhone in the car.
stl should be flipped before printing an requires supports on the overhang. I have included a 3mf file, where all of this is already setup.
Adding a 45 degree side from the overhang to the quadlock surface could probably do away with the support need, but unfortunately I could not get this done easily as the quadlock part is imported from a mesh.
Also you should probably drill a hole through the middle before installing the magsafe adapter, as it's a tight fit.
