I remixed the Vacuum Cleaner Flexi Nozzle Adaptor to be compatible with 35mm (Karcher in my case) vacuum cleaner.
Also I made the hole for connecting the valve smaller, so that you can use a piece of filament (use 1,75 drill bit to make the hole exact size, use a lighter or a soldering iron to make the filament thicker on the ends) instead of a screw.
