Adjustable dual-hose portal air-conditioner upgrade

With summers roaring heat, I finally wanted to upgrade my Air-Con to a dual-hose. Since I couldn't find any fitting for my AirCon (Medion Life P1002), I adjusted grauerfuchs's adapter to fit my air-con.

His adapter also didn't utilize the full intake, blocking lots of it for bigger intakes. So I adjusted the adapter to a pyramid shape, retaining more of the intake and preventing overheating of the aircon.

How to adapt

1. measure your intakes size. Mine is 245mm*275mm

2. gather your hose size (OUTER DIAMETER!). Most are either 150mm or 156mm.

3. open the .scad file in OpenSCAD

4. Enter your values in the top: sizeX, sizeY and tubeDiameter

5. Optional: enter the thickness ("width") of the print. I used 4mm as default so that 3mm connectors from cutting the object to fit on the print plate work fine.

After printing, just glue the files onto the existing filter on the intake or replace the filter with the intake. I recommend sticking with the filter, especially with outside intakes lots of pollen could otherwise block the air intake and damage the air-con.

The provided .stl files are for a 156mm hose with 245mm*275mm intake, fitting for a Medion Life P1002 air-con.

Print Settings

I used the following settings for printing:

• Support: Organic

• Brim: yes

• Material: PETG (I suspect that PLA would also work, but with the heat coming from the lower radiator it might get problematic)

• All other settings are whatever you choose.

• I advice printing it in 2 parts with the cut face down. This allows you to have more flexibility in the hose diameter (see Installation instructions)

Installation

I highly recommend using thick double-sided foamy tape to install the adapter onto your existing filter, if that exists. If you print the adapter in 2 parts (which is recommended), my advice is to glue the parts together with the hose already installed and clamped to the part. Doing it this way makes sure that the hose actually fits inside the part, some hoses are very tight fits. You can use automotive epoxy or hot glue to expand the part a little bit.

I added V2 which is a complete Redesign using Hulling instead of a pyramid shape. It now looks a lot better and has way less problems than V1.
