UPDATE: Version 2 of the drinkpond has been out in the wild for quite a while now and I haven't received any complaints whatsoever. If you want to have a drinkpond, you should chose version 2 over version 1.
UPDATE: Version 2 of the drinkpond available now with 5mm higher water level and a cutout to reduce amount of plastic needed and hopefully reduce ABS warping. ATM untested, print at own risk.
This is a cat drinking pond that takes soda bottles (like coke, pepsi, etc) with a pco028 thread as a reservoir. The water level is kept constant without the need for permanent monitoring on your side.
All corners and edges are nicely rounded so your tippy-toe doesn't hurt itself - also it looks much better.
L*** the cat: "Yay, I can haz water purr*"
Got inspired by the "pond for small animals", my thing is a complete redesign though.
Printer Brand: RepRap
Printer: MendelMax 1.5+ Custom
Rafts: Doesn't Matter
Notes:I got good results with PLA, .35mm nozzle at .2mm layer height. I also used 4 perimeters and 5 top layers to make it watertight. You might get away with fewer layers and perimeters, but I didn't want to take a risk.
Print the cat-drinkpond-v2.stl file:
Please make sure to use a "food safe" plastic to not put your pet's health at risk. Extruding the plastic through a brass nozzle might increase the lead content of final product. (Also see the discussion below)

Then go and find some empty PET-bottle (no pun intended) that has a PCO028 thread (coke bottle, or similar thick-walled bottle). Fill the bottle with water and screw it into the socket of the pond. I would suggest the small .5l or the 1l size at max. any bigger than that and the pond will probably tip over quite easily.
I designed this thing to be massive and survive everyday use: before you print, double check the gcode so you don't waste plastic on a useless non-watertight print.
If you already have a bowl that you like to use with a bottle as a reservoir you can also print the cat-drinkpond-tower.stl, which basically is a stand for the bottle with some openings. You'd have to tether the bottle somehow to avoid that your cat tips it over, though.
