Portable Air Conditioner Air Exhaust Passage Adapter for Small Windows (Adjustable)

Why Needed

Most portable air conditioners ship with a set of window sliders that allow them to be mounted to windows with length between 19.4 and 62.2 inches (49.3/158.1 cm).

My window is shorter than that -- 15.2 inches (38.6 cm).

You could cut the included mounting kit, but that would limit its reuse in the future.
 

Compatability

This adapter was designed for the air exhaust passage that came with my Midea MAP08S1XWGR-T, part number 12120600A23603.

It may fit the air exhaust passages for other Midea Portable Air Conditioners.

I would be surprised if it worked with other brands.  Feel free to remix.

The Midea exhaust hose is about 5.9" / 150 mm in diameter, which seems to be a standard size (based on 2 other models here on Printables).  If your hose is the same diameter, you can pick up a Midea Air Exhaust Passage from Encompass for $7 + shipping (at the time of this writing).  That may be easier than remixing.
 

Before Printing
 

1. Measure the open length of your window and divide by 2
   
   Note: round down – it's easier to cover a gap with tape than to reprint a model and/or cut the model that you printed
    
2. Load Midea-6.3mf into your slicer
    
3. Adjust the x position of part B with respect to A so that the overall x-length in World Coordinates matches the value from step 1
   
   Note: if you have to move B so much that there is a gap between it and part A, just copy and paste another part B into the model to cover the gap

Note: this adapter is designed to be used with a window that is only open 90 mm.  This is because my window is on the ground floor and it locks at 90 mm to keep out the robbers.  I think that the model can be remixed to work with wider gaps, but it's probably easier to just cover the cap with a piece of cardboard (or fancier material, if you have it).

2 Adapters

2 Clips
 

Note: I used Fiberlogy Easy PET-G
 

After Printing
 

1. Connect the two adapters together using the clips
    
2. Reinforce the connection by placing cable ties in the slots in the thick inner arms and tightening them (do not overtighten)
   
   Note 1: You can see one of these cable ties in the example picture
   
   Note 2: There is a second set of slots for cable ties in the thin, outer arms.  I ended up not using them as they interfere with the mounting of the air exhaust passage into the adapter
    
3. Insert the air exhaust passage into the adapter, the same as you would into the included mounting kit
    
4. Place this assembly into your window.  Secure with tape as needed
    
5. Attach the exhaust hose to the air exhaust passage

Backstory

My makerspace tends to be the warmest room in the house.  In the winter, I can just open my window and let in some cold air.  In the summer, I have the choice of being uncomfortable in my too-warm makerspace, or being uncomfortable (and making my wife and children uncomfortable) in the too-cold rest of the house.  So I'm trying to add a small portable air conditioner to my makerspace so that I only cool the room that's hot.
