This is a suction cup based mount for the Eufy 2K cam that I cobbled together taking inspiration from the source item. The other portions were designed by me.
Suction cups (50mm) can be purchased from Amazon here.
The mount works. I am using it myself. I hope you find it useful.
The author remixed this model.
The Eudy 2k cam base and a portion of the arm were repurposed and attached to my suction mount plate.
