I guess it depends how to value your time. For me a couple of hours to avoid paying £400+ for a decent cordless vacuum seems worth it.

I’ve actually fixed this vacuum cleaner numerous times! Not always with 3D printer parts though.

And it can be fun to fix something. I felt very rewarded after I replaced our kitchen machines worn out gears, by designing and printing out new identical ones.
