Some adaptors - round to round in various diameter

thingiverse

I designed these parts primarily for my own use, but now they're available here. During summer, I rely on my mobile air conditioner, which blows hot air through large tubes outside. However, like so often, those tubes aren't long enough and come in various diameters. Here are some of my adapters. If you need different diameters or lengths, feel free to contact me via the comment field - that's the easiest way. Please also let me know if you need nipples for holding and their position as well as diameter. The Staubsauger_Adapter_V1 is designed for my Dyson vacuum cleaner; I hope it fits yours too.
