This thing allows you to hang a Wyze camera on the side of your typical 40b aquarium. The lip may fit the edge of other aquarium sizes too.

The small hook on the thing allows it to clip under the ledge of the edge to lock it in place.

The Wyze camera slides in from the side facing the aquarium so your cats can't accidentally pull it out.

If you rotate it so that the side with the triangle brace is flat on the print bed, then supports should be minimal.
