Extender for Car wireless vacuum cleaner

It's a simple extender for a compact vacuum cleaner.

The vacuum has a floor brush, but it is very uncomfortable to clean the floor without an extender, as you have to bend or kneel to reach the floor. So I was forced to make an extension tube for it, as I did not find a ready-made model.

 
The model total length is 250mm. 

It's a stackable model; you can print several ones. I use two or sometimes three ;)
Here is 0,4 mm classic profile with added ironing.
