The external vented part of my cooker range broke but the butterfly vent hinge was left intact.

I couldn't get a new one without having to remove the whole lot including messing with the through-wall parts so I made this one in TinkerCad.

It fits a 4" vent and is made to sit flush on the outer wall where the old vent exited and had enough room to allow for the butterfly hinge to move, open/close. It could be siliconed in place or screwed.

A piece of material mesh could be added to exclude smaller insects.

I used auto brim and 'thin tree' supports in Creality Printer. All the rest was standard K1 settings.

Fiddle with it, Im sure it can be improved upon.
