Henry vacuum cleaner - request

[Newlands]

Can some kind person with a Henry do me a favour? I want to know the outside diameter of the nozzle on the end of the flexy hose so I can print a hose adaptor. I've tried looking on Numatics website but all they give is a nominal hose diameter which is not going to be accurate enough for a decent fit.

Mine is 35mm

Any good to you?

I'm assuming you don't have an external caliper.

I have, but I'm in Sussex and the Henry is on the Isle of Wight, and my arms can't reach that far

Thanks - an impressive collection of attachments. But I can't measure from an stl file. Opening the file in Fusion it shows the diameter of around 260mm.
Opening in Bambu Studio indicates an OD of 31.5mm but clearly doesn't like stl files, Prusa Slicer shows 26.5mm, both different to the dimension @Seadog mentions, and different again to the nominal dimension Numatic says on their documentation which was 32mm.

Right I've had to down tools for this important mission but I've measured Henry's nozzle and have these measurements.
This is my old workshop Henry


This is the missus one



The two lower photos show a very slight taper.
Now I think the lower ones are an original genuine hose and the top battered one an eBay copy.
Can you make it from something flexible?

I have a George vacuum and the connecting spigot diameter tapers from 38mm at the hose connection to 37mm at intake position.

As its still pi**ing down and blowing a gale im bored so here you are, this is a genuine Henry nozzle, not perfect round though

not perfect round though

Did you tread on yours too?

We should not wonder that everyone is getting different measurements.

From the factory, it is the _inside_ of the hose cuff that receives the attachment. That is uniformly 32mm.

As the item is to be 3D printed, does that not offer an opportunity to design it in such a way that it will accommodate a range of diameters?

You could perhaps take inspiration from this type:

Most nozzles have a taper so that they lock, parallel dimensions would fall out.

It might have been chewed by one of the dogs

Many thanks for all the responses - exactly what I need. For some time I've been using offcuts of waste pipe and masking tape to attach my sander which results in some very very bad language.
