Suggest drill and tap 8-32 or better 10-24 in the middle of the vent,
then use margarine tub secured with stainless steel round- or
pan-head machine screw and flat washer.  If you want to work it
without tools, use brass or bronze  round-head screw instead, cut
down a washer and soft-solder or braze it into the screwdriver
slot.  Or you may find a small knob with brass insert that you can
attach to a cut-off brass screw.  In that case you're likely looking
at 1/4-20 for the hole. Drill a wooden block or dowel section as a
spacer between tub and vent so you can snug the screw down without
injuring the tub.

Provide a stub screw if necessary to plug the hole when the fridge is in use.

Same procedure for the regulation cover, probably sans spacer - but
they perish in the sun, so the tubs are cheaper over time.

Yours,
