Water bowl feeder

Keeps a water bowl topped up. You provide the bowl and the water bottle. You must drill out the cap. See instructions.

There are a few of these water bowl things on Thingiverse. Most of them print the bowl along with the bottle holder. I wanted one that would clip to the side of the bowl I already have. I also decided to incorporate the bottle's own cap instead of printing a thread. STEP and Fusion 360 files provided if you want to vary the dimensions.

Updated: version 2 files have a hook on the lip to stabilize from side to side nudges, if your bowl has a flange like mine. The model was also redrawn to simplify the design history and put more dimensions in parameterized sketches.

Updated: v3 cap holder has an extended back wall to provide a larger contact patch when printing in two parts. Use with the v2 tub. Single print model should not have a delamination issue.

Updated: v4 replaces the open tub with useless side vents with a solid holder with a full hole to provide more surface area for the cap to grip.

If you have a Dremel, check out my bottle cap hole drilling jig to adapt your bottle cap.
