There is a similar drink station for insects here on Makerworld that I printed. However, it didn't work for me because no water flowed into it. The drinker always dried out.

So I tried a few times and ended up with this model.

It works great with glasses that have a diameter of ~78mm. I used the cucumber jars you can see in the pictures, but of course any jar with this diameter will work.

I printed this in PETG. 

Fill the jar with water, place the drinker in the center and quickly turn it over and place it in a flat place in the garden. For me, water always runs as soon as it starts to dry out. The drinking trough lasts about 5 days directly in the sun, then you have to refill it with water.
