Rimmed water bottle ATO???

[pulpfiction]

I have a 20 gal Aqueon and it seems impossible to get a water bottle method to work. Are there any 3d printed water bottle holders to hold a water bottle on a rimmed tank? I tried cutting up two water bottles but my rim is too thick. None of the water bottle holders that I can find are made for rimmed tanks. I don't want to install an electrical ATO.

I tried one of those. They don't work for rimmed tanks.
