Gravity fed cat water dish

I wanted to make a self feeding water dish for our new cats that could hold a large amount of water. All the others I found on here seemed to be built for 20oz or smaller bottles. I decided to make one that could attach to a 32oz or 64oz Gatorade bottle(they have the same threads). This was not the first version but it uses about half of the plastic the original did. It requires a build area of at least 175mm x 140mm, not huge, but not for smaller printers.

Also, for best feed rate I've found that I tighten the full bottle all the way on, flip it over, then unscrew it about 1/4 turn. The bubbles flow freely then. The 32oz bottle lasted about 2 days with two cats drinking from it. So far, I've been the only one to knock the 64oz bottle one over, the cats have yet to knock either one over.

Just revamped the dish to address a few things. The one ending in ver2 is the newest at this point. It has a less pronounced lip and fewer sharp crevices, both are for easier cleaning, I found mold was able to grow in those hard to reach areas. Also, I beefed up the neck where the bottle attaches, broke one on the old model(it still functions, but just wanted to address it). Finally, it's a bit more low profile, which, as it turns out, uses only about 80% of the plastic that the old one did and thus prints in 80% of the time. Finally, I made the stabilizer bars a bit smaller, they work just as well and unlike the older model, I haven't had them warp during printing on my non-heated bed. Enjoy!!!
