I'm inordinately proud of this one because I designed it in Sketchup myself, so there's no one to blame but me. I'm trying to get to a printable desktop fountain that you can run on your desk without worry of spillage. Right now, I've printed 2 prototypes that work but are still sub-optimal. Since you're working with water, print with 100% infill. I had to push out some plugs that developed in the holes with a drill bit, but it wasn't too much effort. The design is more or less sound. My original concept was to use a pump with an input & output so I could regulate flow. I ended up using a submersible pump in the test video. A two way pump really is necessary here to get the desired effect. http://www.youtube.com/watch?v=byHLTwXhLAA
