This Traveling pet bowl is designed and printed with form and function in mind. The Strong and Pretty profile is .2 layer heights and printed vertical with no supports. The file is saved at 85% scale for time and height restrictions, can be increased to max height of 252mm. To use the bowl just hold the printed bowl under the water flow with the square edge oriented downward and the water will flow into the squared of chamber slowly. one the bowl is placed flat the water will fill the bowl, if filling is to slow give the bowl a little shake and it will fill faster. As your pet drinks the water will continue to fill the bowl. This model is designed with travel in mind and that you will fill the bowl from a water bottle on the go, or a sink for home use. The volume ow water is largely dependent on the scale of the printed bowl. I have printed the bowl at 50% - 100% scale and the the volumes are drastically different. I personally prefer 85% scale for function and size compatibility while traveling.
