Pretty simple design. Clips on the size with some force and doesn't move around. Protects the sides of my porcelain sink so I don't end up with scratches on my porcelain Kohler Whitehaven sink from sink grate. Only uses about 1 g of filament to print each one. I actually ended up just creating it in Bambu Studio using cylinder tool and negative cylinder.
