Hilti VC 10-22 hose adapter for smaller accessories

For my Hilti VC 10-22 vacuum cleaner I have some cheap accessories bought at Aliexpress.

The set of accessories comes with an adapter to put the accessories on the original Hilti vacuum hose.

So, you have the hose, the original adapter, another smaller adapter and finally the accessory of choice. The stiff parts combined is rather long. Not always workable in tighter spaces.

I redesigned the original Hilti adapter to end with a smaller opening to directly fit the mentioned accessories.
