Had an overflow hole in the gutter rainbox that needed a bit of sprucing up so combined the cap that hole and low poly shark to make it a bit more interesting.

See remixed projects to generate correct size hole cap for yours.

I combined, resized and punched a hole in the cap in tinkercad.

I printed it as show in the stl with tree supports but if you wanted to save filament you could split the shark and rotate the cap to get a faster print.

As is it took 3.5hrs to print with my ender s1 running klipper.
