This part is part of the Philips vacuum cleaner brush. This is the main part of the brush mode switching mechanism. In my FC 9154 vacuum cleaner, this part broke, unable to withstand mechanical loads, and as a result, it is impossible to clean the floor without carpeting with the brush. I could not find spare parts for the brush, and decided to print a new part. I slightly guessed the seat for the switch button: in the video you can see how long I was putting it in place. But overall it turned out great.For ease of printing I am posting two files: one with a clean part, the other with supports that make printing easier. After printing they need to be cut off by mechanical processing.Have a good repair.
