Detailing brush nozzle for Makita vacuum cleaner

I got an idea to combine a car detailing brush and nozzle for vacuum cleaner. 

So I took a typical detailing brush that has approx. 34mm diameter of its connecting part (please see the picture) and designed this nozzle for my Makita vacuum cleaner.

Assembling is pretty easy, just unscrew a detailing brush, and make a hole in the middle. then screw it on this nozzle.

It has same dimension on the side to be inserted to the cleaner, so you can use it on either directly or using an optional flexible hose.

I personally use it with CL282 + flexible hose (191E30-3) as shown in the pictures. It's useful for car interior cleaning.

The straight pipe part of the model has diameter of 32.0mm and that what you want to achieve on your print (bottom to be 31.0mm). Due to shrinkage, you may need to adjust the diameter by scaling. In my case (Extrudor Greentec PRO Carbon), 100% scale provided a good result.
