The brush attachments of our Philips vacuum cleaner have a ridge which can slide into a slit on the vacuum cleaner body. However, after much use this ridge was so worn that it did not stay inside the slit anymore. 

So I designed a replacement piece for it so we can store our hose/tube again.

Notes: 

1. you will probably need to file down the remainder of the ridge before you can slide over this attachment
2. I modelled this for our vacuum cleaner. I added the Fusion360 file so you can tweak the model to suit your own vacuum cleaner.
3. Needs a little bit of build plate support.
