Watch Holder Kayak

Watch holder to be applied via suction cups to the Kayak.
Since each boat has its own shape, I inserted various 3D models with different angles to adapt to the attachment surface.

The two suction cups are 40mm in diameter and have a M4 threaded pin.

They are fixed with two M4 nuts.
