I needed a wide and thin nozzle for my Dyson V8 so, here it is for others to enjoy too.
The ridges under the nozzle should have helped distribute the airflow evenly. I'm not sure they help but at least they look cool. I will try to post a simple version too.
Please let me know it it works well or if you think it could be improved somewhere.
Feel free to propose different kinds of tools you could use, I would like to extend the range.
