I use this to push hot air into my Samla DryBox https://www.printables.com/model/146367-ikea-samla-45l-filament-buffering-dry-box-v2
Thanks to @moggieuk (author of HappyHare) for this great idea.
Update: In the first version the adapter was exactly 60mm in diameter which was too small for the flex alu tube i have. Its now 61.5mm in diameter. If you need a different size, send a PM.
Here the flex tube i am using: https://www.amazon.de/dp/B08F5GZN2B
printed with ABS, 0.2mm layerheight, no supports
I also made some adapters including valve for the SamlaBox and will publish them soon.
