Exhaust adapter for rheem heat pump water heater with 24" diameter tank. Secure to tank with screws, magnets, or double face tape. Fits 8" ducting. printed in petg.

better than the original adapter since this channels all the exhaust air to the 8" duct, vs just blocking the other exhaust holes.

better than other versions of this, in that it prints in one piece on the bambu. no need to split the part and reassemble.
