Really basic Miyoo Mini V2 charging stand made for the following magnetic USB-C cable (but I guess it should be compatible with some other brands as well) : https://www.amazon.fr/gp/product/B09CD3LHJZ/
The assembly should be a tight fit, but if there is too much room you can also use a M3 screw with a heat-set insert.
Update: Added two variants for the top part: one with a smaller front notch, and one with no notch at all.
