About this 3D model

A replacement design for the protein skimmer on a eheim 1260 pump. The old skimmer fan broke off into little parts over time. I designed the skimmer to be easily replaceable. Remove the old fan and glue on the threaded inner part on the rotor. The needle skimmer can now be screwed on the rotor and replaced when needed without glueing or cutting. The thread direction was designed in such a way that the force of the pump will tighten the combination.
