Henry Numaitc hoover/vacuum 35mm conversion nozzle

This nozzle replaces the original Henry 38mm nozzle with a 35mm one so you can use it as a shop vacuum. It is made quite thick on purpose, in order to withstand rough handling. I suggest printing it vertically with the vacuum side down, in PETG, with 5 perimeters on a 0.4 nozzle.

It allows you to use attachments intended for 35mm OD shop vacs directly to your Henry vacuum without the extra bulk, weight, and length of an adapter.

I have tested it with the following models:

Assembly

You must remove your current nozzle and install this one in its place. You need both the hose end cap and the original ring. This nozzle only replaces the original nozzle part but not the rest of the assembly. If you are missing the other parts, there is a complete, 3d-printable set of those too.

There are two retaining clips on the side - push them in with a screwdriver while pulling the hose away from the nozzle. After a bit of struggle, you'll be able to pull the hose out of the nozzle.
