Vacuum Attachment Adapter for Nilfisk Multi II 30

This is an adaptor for a Nilfisk Multi II 30 shop/heavy-duty wet/dry vac to fit ebay tools. Turns out genuine Nilfisk tool packs for e.g. car interior and uphostery cleaning are rare as hens teeth and expensive if you do find any. So I got some from ebay that claimed to be compatible, only to find they were definitely not! A lot of measuring (especially the taper angles) & a bit of Fusion360 profile spinning later, I got a working adaptor design.

I ended up gluing the adapters into the tools as though they fitted snugly, half the time when taking the tools off the adapter would be on the hose end, the other times in the tool. A pain when I wanted to use the extra tube sections. A bit of superglue bonding them in to the tools solved that issue!

This is rather a specialist part so it's only going to be of use to someone with a Nilfisk shop vac and a no-name pack of ebay tools! But if that's you, here you are...
