Amcrest camera IP3M-HX2. Have one of these and the screw hole in the back either partially melted or just broke\cracked. Had it for a while.
Took apart the base. Used a flat head to pull up the rubber foot and saw it was friction fit clips. The tape on the bottom rubber part was sufficient to put back on when done yet didn't actually need to take it off. Was looking for hidden screws, didn't find any.

If printing, please be mindful of the hollow parts underneath. The center hole is to fit into the existing space. The chamber around the outside is to fit the rubber ring. This ring makes it so the camera can be rotated, yet keep its position. Not a new addition of mine, just something the camera's mechanism already used.

The part that the screw on the back goes into has been broken for a while. Finally opened up Tinkercad and made a lazy low poly knockoff.
Just put it all back together and camera is hanging upside-down by the internal magnet. So far seems good.
