**Feel free to comment, I will respond within a day, and usually within an hour or two** **Feel free to remix, but please credit me.** ***Update: Part 2 of the fountain had some issues, so I changed it. If you downloaded this before 2/27/2021, please redownload part 2.*** ***Update: The fountain barely works because the bottom tank doesn't hold enough water. I have changed the tank to be larger. If you downloaded Part 1 (Lower tank) before 2/28/2021, please redownload immediately*** This is a nice-looking tabletop waterfall fountain that looks like its about to overflow, but at the last second, it drains. The water is pumped from the lower tank into the upper tank, where it comes within half an inch of overflowing, before going out the spout at the top. The water falls into the catch tank, again rising, until it reaches a quarter of an inch from the top. Then, it drains through the rectangular hole. The fountain is designed so that you can control the water flow rate (or really, tank drain rate). There are drainage holes in the bottom of the upper tank. Cover at least enough of them so that the water level inside the upper tank rises. Then, cover or uncover more to control the flow speed. More holes covered = faster flow rate. However, leave at least two holes uncovered to allow the water to drain when the pump is turned off. Similarly, there are four drainage holes in the catch tank. Cover different numbers of holes for different flow rates. However, make sure at least one is still open to allow the water to drain when the pump is turned off.
