How about a “stable position” mount. Don’t care as much on how it works, but the magnet approach leaves too many opportunities for shifting the camera. It makes removing the SD card a guaranteed resetting of your view and a simple tug on the power cable can do the same. Also of note, if you use the magnet mount on a ceiling or wall with vibration (mine is due to air handling unit), the camera is like to fall off.
It seems like there is an opportunity for a slide in style mount considering the edge condition of the current grey base. I don’t 3D print, but I could design something if someone else wants to produce it. It could even have an embedded medal plate to take advantage of the magnet (a belt & suspenders approach).
