Two jobs bring Meaco owners here. The first is a snapped or stripped hose connector where the exhaust pipe screws into the machine, which Meaco does not sell separately. The second is adding a second hose so the unit stops pulling cooled air out of the room. We hold print-ready files for both, print them to order in our Basingstoke workshop and post them tracked across the UK.
Independent community designs by burg93, scyt1, ejytsu and Celizior. The Meaco-specific conversion designs are CC-BY-NC and use the one-copy customer-directed service described below; the connector and universal intake designs use commercial-friendly Creative Commons licences. Hark Tech manufactures the selected files but does not design or modify them.
A single hose blows your cooled indoor air outside. That air has to be replaced, so warm outdoor air is pulled in through gaps around doors and windows. You are cooling air just to throw it away.
Because warm air keeps leaking back in, the unit runs longer to hold the same temperature. On the hottest days, when you need it most, a single-hose unit can struggle to keep up.
A second hose feeds the condenser with outdoor air instead of room air, so the room stays sealed and cools faster. It is the same principle used by higher-end portable units that ship dual-hose from the factory.
These two community designs use CC-BY-NC licences. You review the original design and licence, appoint Hark Tech solely as your manufacturing agent, and confirm that the single copy is for your own personal use and will not be resold or used by a business.
A two-part top and bottom intake adapter made specifically for the Costco-exclusive Meaco A-COSTCO12K-PRO-CH. It is not a general Meaco or Cirro part.

The creator describes this condenser plenum as untested and modelled for an older MC-series intake filter with a 150 mm hose connector. Check its shape and measurements against your unit before ordering.
CC-BY-NC · untested WIP · one personal-use copyCurrent Cirro / MeacoCool Pro: neither design fits the A-MC16000-INVPRO-EU chassis, and we have not found a downloadable design for that casing.
These designs use commercial-friendly Creative Commons licences and follow the normal print-service checkout. Order any part on its own; prices update live.
The connector where the exhaust hose meets the unit, remodelled after the designer broke his own during a heatwave. Fit it with a hose clamp: the printed threads are approximate, which is exactly what the clamp is there for.

The cheapest way to add the second hose. It is not Meaco-specific, it adapts the intake side of most single-hose portable units, so check your intake before ordering. Small, quick to print and easy to post.
Approx. 77 g printed · from £6.90
The bigger option for the window end, joining a 150 mm intake hose to a window cover or panel. Worth it if you want a tidy permanent setup rather than a hose hanging out of the sash.
Approx. 460 g printed · from £30.00Connector sizes vary across the Meaco range. Measure the diameter where your hose screws into the machine before ordering, or send us a photo on WhatsApp and we will check it.
Our pick for the machine adaptor. It sits against the warm side of the unit, and PETG handles that far better than PLA for very little extra.
Fine on the intake side, where nothing gets hot. We would not put it on the exhaust connector of a unit that runs hard all summer.
The most heat and UV resistant option, printed on request. Pick this if the unit sits in a conservatory or strong direct sunlight.
Material prices shown are for the MeacoCool MC machine adaptor. Tracked postage is calculated in the cart from packed size and weight, free on orders over £40, and the delivered total is shown before you pay.
Yes, for two specific chassis. The Costco-exclusive A-COSTCO12K-PRO-CH design and an untested WIP design for older MeacoCool MC units are shared under CC-BY-NC. For personal, non-commercial use, you can review the creator’s licence and appoint Hark Tech to manufacture one physical copy for you. Neither is for the current Cirro A-MC16000-INVPRO-EU chassis.
The designer made it for the MeacoCool MC series and notes it may suit other units with the same connector. Connector sizes vary across the range, so measure the diameter where your hose screws into the machine before ordering, or send us a photo and we will check it for you.
A single-hose portable air conditioner pulls air from inside the room to cool its condenser, then blows that air outside. That leaves the room at negative pressure, so warm unconditioned air is drawn back in through gaps around doors and windows. A second hose gives the condenser its own outdoor air supply, so the room stays sealed and cools faster. It is the same arrangement higher-end portable units ship with from the factory.
For the MC machine adaptor you need a hose clamp to tighten it down, which the designer recommends because the printed threads are approximate. For a dual-hose conversion you also supply one standard portable-AC hose for the new intake, a cheap and widely available part. Message us before ordering if you are unsure which hose fits.
PETG for anything that sits against the warm side of the unit, which includes the machine adaptor. It costs a little more than PLA and copes far better with heat. PLA is fine for the intake side in a shaded room. ASA is the most heat and UV resistant option if the unit sits in strong direct sun, and we quote that on the order page.
There is nothing to upload. Commercially licensed connectors and universal parts use the normal order page. For an eligible CC-BY-NC Meaco-specific design, open its original model and licence, appoint Hark Tech as your manufacturing agent and confirm that the one copy is for your own personal, non-commercial use. Tracked postage is calculated in the cart from packed size and weight, free on orders over £40.
MC machine adaptor from £16.50, universal dual-hose intake adapter from £6.90. Printed to order in Basingstoke and posted tracked across the UK: postage calculated in the cart, free over £40.
