Shelf mount for Ezviz surveillance camera

I wanted to mount the surveillance camera on a slightly higher shelf to monitor the whole environment and above all the children's play on the floor but the downward angle allowed by the camera is rather limited so I designed an inclined support on which mount the bayonet support supplied and ensure full stability of the whole, without having to screw it onto the wall or onto the shelf.
Print even with a rather high layer thickness (0.28 mm), with a number of at least 4 perimeter walls and 4 upper and lower layers, even with a low filling of 5-7%. The dimensions of the round recess on the upper face allow you to fit the bayonet accessory supplied with the cam without having to use glue or screws.
