Bought myself Sculpfun S9 laser engraver and wanted to have removable hose holder for air assist so I designed it. It is designed for 6mm silicon hose (used for aquariums), if you have any other dimensions of hose I have included Fusion 360 file so you can modify the holder. It clamps on stock cooling fan (see photo).
Printing details for 0,4mm nozzle:
I recommend 2mm skirt or brim for better adhesion.
