Hi again!
Here's wall mount for Xiaomi liquid soap dispenser. Design is very simple but the thing is strong enough to hold the dispenser full of soap. By the way, there are many soap dispensers today, so if yours diameter is about 73-74 mm it will fit.
This also can handle anything you can mind :) Feel free to modify it to fit your needs!
