There's starting to be more and more models for the Snapmaker U1, but I still couldn't find anything to mount the Blink Mini 2 camera (https://a.co/d/0cNVS6B8).  I haven't done much modeling yet, but figured I would take a shot at it.  The mount fits snugly in the round rubber rings and then the camera snaps into place with it's own base plate.  I realize that a different design will be needed once you have the top cover or make your own, but I'm not to that point yet, so this works for me for now.

It works for me, but I'm happy to get any feedback and I'll try to find time to implement it.  Also feel free to make changes yourself.
