Francis Turbine Shower Head

Print parts at highest quality possible. Strict tolerances are built into every design, so any misalignment of your printer can lead to imperfect rotational bodies that will jam rotation. Clean each part carefully and break in rotating parts to make them run smoothly from the start. My first print job was done at 0.1mm layer height and 25% infill. The shaft printed with 100% infill, while housing, runner, and cover plate required support structures - a minor inconvenience since all other parts came out perfectly without any issues. Support structures touching the build plate will do just fine. The internal blades in the housing part provided enough support that only slightly imperfect ceilings due to large bridging distances were visible. To print the handle, lay the flange flat on the build plate and add brim support for extra adhesion. The handle is designed to fit a standard European thread, which I believe is the only one used - don't ask me for specific size or specs, as I simply took measurements from the original shower head. Adding other sizes in the future is definitely possible if requested. No gaskets are currently used, but parts fit together tightly enough that no water sprays out. A little bit of dripping water isn't a big deal. Use M3x10 and M3*16 machine screws for assembly. I also tried countersunk head wood screw M3x12 and it worked great - just be sure to drill the holes slightly to get a proper cone fit.
