Flexible Duct Couplers for Portable Air Con 130mm (5.2 in)

thingiverse

I'm sharing three types of flexible portable air duct couplers that are perfectly suited for connecting 130mm OD PVC concertina pipes. Since pipe sizes can vary depending on the brand - my Delonghi unit uses this size, but other brands use different diameters - I've attached these three versions to help you out. The additional 2m duct I ordered, which isn't an OEM part, surprisingly had a left-handed spiral twist instead of the right-handed twist that came with my unit. So, I've included three versions to cater to your needs: * A right-hand pipe to right-hand pipe coupler (female threads) * A right-hand pipe to left-hand pipe coupler (female threads) * A left-hand pipe to right-hand aircon unit fitting (female and male thread) Each of these couplers has an "L" or "R" marking on the ends, making it easy for you to assemble them correctly. Note that only the last two types are shown in the photos because I couldn't use the first type. It's worth mentioning that each part took about 15 hours to print on my Prusa printer. The final photo also shows my window adapter duct, which can be found at https://www.thingiverse.com/thing:3934575
