This is a hatch handle for Goiot Evolution hatches on our Amel Super Maramu #153 but can fit many other boats fitted with these same hatches. Both left an right handle are included in the model. It is designed to the exact same size as factory handles so I recommend printing at between 100.5% to 101% scale to make fitting easier. I printed it at 5 layers top and bottom and 8 walls and 35% infill in ASA since its high exposure to the sun and it turned out stiff enough but I think I would print it at a higher infill or more walls to make it more sturdy in the future. Also a large skirt immensely helped avoid warping.
