This latest garden bee watering station features a tray subdivided into cells with a screw-threaded port in the centre into which you can screw a standard 500ml Coke bottle (and probably others, but I haven't had any other bottles to test it with!)
If you don't have a 3D printer but you'd really like one of these please send me a DM and we can arrange for me to produce one for you, or check out my Numonday store:
