I needed that kind of nozzle to vacuum our sofa so here it is. I created nozzle model myself firstly for Xiaomi G20 Lite, since we no longer have this vacuum i had to remake it for our new vacuum. I used https://www.printables.com/model/1138987-laresar-v7-generic-adapter and built my nozzle on it. Enjoy!
The author remixed this model.
Remix used for mounting the nozzle to the vacuum.
