Diy Adjustable Length Window Vent

Finally moved my GF inside to the mother-in-law suite. I’ve seen some Diy versions of the window vent, but why not employ my laser.

Cut from Home Depot Baltic Birch sheets measuring 2.77mm so the inside panel fits very snug in the outer panel. Also, use the quick disconnect dryer vent holder from Walmart for the hole. This was a very snug fit (used WD40 to make the vent slide in, but I’d maybe cut the hole very slightly larger next time). Didn’t measure how far it expands but I know it’s more than 40" as build.

I still have the CDR and DXF files if anyone needs them as well.

Full disclosure, I used my large 500x700mm laser to cut the pieces, but you could use the GF and just cut individual pieces.


Nicely done!

Nice! It looks like it works just like the steel one I bought from Amazon. The only thing I added was an edging made of air conditioning hose insulation (like a pool noodle) slit up the side and placed along the top edge where it meets the window. I find that gives me a pretty good seal where surfaces may be uneven.


Much better than my overlapping loose pieces of plywood.

I used a piece of foam window sill along the top as there was a 2.77mm gap right above the vent due to the adjustable function. So far so good.

Oh, very good! You’ve hidden it very well. Your solution is certainly a lot more elegant than mine, which is pretty industrial looking.

Nice work! Can’t believe you still have that card over the escutcheon…

Oh, that’s a good idea with the pool noodle.
I need to build out my venting solution this weekend. I’ve either not had a chance or it has been raining. I’ve just been tossing the hose out the open window and bringing it back in when I’m done.

Put it back on there during the garage to in-law suite move. Lots of writing on the other side when I was doing manual calculations of non-crumb tray engraves.

What? That’s not how the GF was designed to work?

Well, I did add a pillow to close the gap. :wink:


I’ve got to know what it says next to the light switch!

ha ha ha…nice! So far, there has only been one night I was lasing with the window cracked and the room started filling up with bugs. It was pretty hot that night (I’m in Mississippi and in the spring, we could have an 80 degree night, or it could be a crisp 56 like this morning). The LEDs really attract the bugs!

The pillow hasn’t moved since November. I really need to finish that up. The saving grace is that my “back yard” is only about six feet wide with an 8 foot block wall. There are two gates on each side of the house and three of the four are also eight feet high. I haven’t had any problems with people climbing in the window. :wink:

“Light switch for motion activated light.”

Exciting, yes?

When I bought the house every light switch and special feature was labeled. Since this isn’t in a living area I never pulled off the label. This room was originally designated as the “messy art room” for things like paint and clay. So far it has only been home to my GF and the rack for my home automation stuff. Some day I’ll finish moving in. :stuck_out_tongue:


Well, now you MUST put up a little sign by that room’s light switch that says just that…“Messy Art Room” ha ha


I did put up my first draft of the “Warning, do not look into laser with remaining eye” sign next to the switch. The second draft is on the door to the room.

I’d love to make this for my place… Way better than my single sheet of MDF and folded cardboard lol

Nice job can you share the files

Small svg is up under my original post. Not certain how to make it larger… file was made for 2.77mm Baltic birch from home depot.
