Steam Jet Ejector
thingiverse
Based on http://de.wikipedia.org/wiki/Wasserstrahlpumpe and http://en.wikipedia.org/wiki/Injector, follow these instructions for printing a water pump: attach to a water pipe and create vacuum. Ensure all connectors have an outer diameter of 15mm. For V2, print with SKEINFORGE using "Exterior Only" support material option to avoid sharp edges. In V3, include small support structure; print with vacuum connector upside down before removing exterior support strips (leaving the stabilizer wall inside intact).
