This facilitates a small, flexible nozzle for my Parkside PNTS1400 wet-and-dry vacuum cleaner. It fits on the end of the normal hose, and a 15mm o.d. flexible pipe pushes snugly into the other end. The holes for the hoses are slightly tapered for a close fit.
Please regard this as a starting point for your needs - you will almost certainly need to adjust the numbers in OpenSCAD to make it work for you.
The yellow nozzle adaptor is shown in the pictures because it was easier to photograph - in reality its dimensions were slightly too small, and it was printed in PLA. The final, black, version was printed in PETG for durability.
The size can be modified in OpenSCAD, but you will need one library: chamfer.scad
Alternatively you could try varying the size of the pieces in the slicer, if you don't want to deal with OpenSCAD - but the tapers may vary between brands.
