I'd like to use one of the K-Edge mounts on my bike. They seem to have a nice wide range of options for both the Wahoo and Garmin locking mount systems.

To start, I would like to just lock my phone onto it with the option of using a Garmin, Wahoo, or Lezyne computer in the future.

Does anyone know of a place to buy the quarter turn locking mechanism from the back of the computer as a stand alone part? I would like to buy a case for my Sony phone and mount it to the back of the case and use it that way for the coming summer.
