Cyclone Adapter to Aliexpress Double Cyclone

Hi
I'm using the Cyclone Dust separator by Dronnn.
see here: https://www.thingiverse.com/thing:2829268

My dust collector underneath has already the mechanical interface to this Cyclone.

On Aliexpress I discovered a double cyclone (wohw !!) and I wanted to know how well that equipment works. So I created a mechanical adapter here which allows you to use the Cyclone Dust adapter mechanical interface with the double cyclone as per link below:

And.. I confirm.. the double cyclone separator works well too !!
