5 Inch Portable AC to 4 Inch Dryer Hose for Venting

thingiverse

I was looking for something simple but nothing here worked for what I needed. I just got a portable AC that didn't come with the ventilation hose, so I went to Home Depot to see if they had any. Unfortunately, they didn't have the right hoses or anything else that fit my budget of under $20. Instead, I picked up a dryer vent hose for $3.00 and two hose clamps for $1.50. This hack converts a 5" portable AC hose into a 4" dryer hose. It's best to print one end piece for each end of the hose for optimal results. You can use this on both ends of the vent pipe, either on the A/C unit or in the window. To cover any extra space in the open window, you'll need an additional piece of plywood or cardboard. This design uses 100% infill with no supports needed. It was created using Tinkercad. You can edit it online at https://www.tinkercad.com/things/h2NsAlSplqt
