Summary

For my sons first grade science project, he made a 3D printable water clock. It consists of a cup with a defined 1MM hole in the bottom (the actual hole prints smaller than 1MM. With one cup of water, the float will rise over 17 minutes. Place the cone into the stand, and position over the catch container. Pour 1 cup of water into the cone, and start your watch. Your mileage may vary with your printer and the accuracy of the hole in the bottom of the cone. Simply turn the float around, and mark your own measurements. Sketchup file included. Like any good new designer, the project is not complete until it is uploaded to thingiverse!
