I designed a little magnetic holder for my 10 ml RDT Spraybottle, so I can stick the bottle to the side of my espresso machine.
In one holder (I use two for my bottle) you can fit two 6x2mm magnets, just pressfit it in the holes and care about the polarity, it is a bit fiddely but its possible
With 4 magnets the bottle sticks perfect to the side of my coffee machine
I use this 10 ml Spraybottle form Aliexpress with an 14mm diameter
