iON SnapCam Lite camera drone mount.

thingiverse

This mount is designed to attach to an LS-210 frame. The camera slides down the rails then clips into the notch. When you want to detach, poke a hex key or something small under one of the corers under the camera to pry it off. This thing is super solid, and you camera is not going anywhere during flight. You might need to push the clip a bit to get it fully in place, but once you've done so it's solid. The mount has a 20° tilt. 4 M3-.5 x 10 screws are recommended.
