The button for the dust chamber broke on my Xiaomi Mi G10 Vacuum, rendering the entire thing completely useless (it would't stay shut). Through the power of 3D printing I am now once again back vacuuming dust and doggo hairs every day!

I tried to contact both the dealer I bought it from and Xiaomi themselves, but rather than just send me a little plastic part in a letter both told me that they do not sell spare parts, and they wanted me to ship the vacuum across the country for repair. This is of course completely crazy and unacceptable from an environmental perspective, however this is also exactly a problem that can be fixed easily and simply with a little CAD design and a 3D printer!
