If you have a G9 / G10 Series Xiaomi Mi Vacuum Cleaner, the standard wall dock that comes with it is a friction fit (works surprisingly well) - however the vacuum slowly starts to slide down and is not designed to also hold the extra weight of having the stick attached at the same time. Whilst Xiaomi sell a separate docking unit for this (which seems to model the standard one that ships with Dyson Vacuum cleaners) i have designed a very simple plate that can be attached to the wall below the standard dock to give it that little bit of support.
I have included an STL and also a scad file if you want to play around with the dimensions or remix.
