After working out that the measurements you have on your files were for the adapters themselves (duh), I printed out the exact size I needed and it works a treat.

No notes, used it to attach a new dust extractor to an old table saw and to add a spacer to a new cooker hood that was a little shorter than the original hose connector.

I’ve printed several of these and had some slight issues with the sizing but I can’t score less than 5 for the sheer effort involved in this many tools.
I have taken to just using the slice tool to take a very thin slice of the end of the tool to test the print and if necessary just slicing a bit off the taper to make it wider where necessary. I realise I could also use the scad models but that feels like more effort 😉

@Ostat Hey Max! Can you make one that is 65.8mm to 21.4mm (Inside diameter)? Unless you already did? I couldn't find it. (edited)
Thanks for all your work, it fits well, but the significantly tighter adapters are too much for my vacuum
@MRV_3888503 if the size is not a good fit, you can use my parametric script to create better fitting adapter.
@Ostat The fit is good, it's my vacuum, it can't manage such a thin tube
Super.
Nice, thorough collection but incomprehensible labeling system—I think it will be easier and less confounding to just build the simple piece I need in Fusion 360. (Why force the metric system onto parts that are clearly meant to match standard vacuum hose sizes manufactured in fractions of inches?!)
@ctgriffi_4049489 there are both metric and imperial adapters in the set.
Fusion is a good choice if you k ow how. recommend you add a small taper on the adapter when you do it. Makes it easier to fit. 1mm/40thou should be enough.
REQUEST: 45mm OD to 1.25" ID.
The male hose end OD measurement is 44.0mm to 45.54mm over 47mm.
I can't use the attachments from this kit:

@Theatrics312_3623426 no longer needed I generated it with the parametric.
