Vacuum cleaner hose adaptor Electrolux Ultra Silencer ZUSG3901 or several AEG models

Hose adapter for vacuum cleaner Electrolux Ultra Silencer ZUSG3901.
You can use this to clean your computer (small places).
You can use it with a hose of 12 outside diameter.

Warning: don't use it to long because your vacuum cleaner will overheat because it's opening is much smaller.

You can also print first the top to see if you hose will fit. Just lower the item in you bed.

I also made earlier another adapter: https://www.thingiverse.com/thing:1800137
