This collection of useful parts and objects is yours to use. All we ask is that you register derivative projects with makeSEA to help track their evolution (privately or publically). You can also use makeSEA to share or sell your designs and mashup your work with the work of others. Keep track, and ensure that everyone that contributes receives attribution. Protected files are makeSEA assets that can be distributed to other systems and link back to the original files at makeSEA. You can distribute these reference assets freely without concern for access restrictions. makeSEA still requires users to login to access the unprotected original files. Share! Print!

Propellers (see also, Brushless Motor v2 re generator) Idea / Motivation Design a parametric propeller, useful as a fan or for an RC-plane. Basically I wanted to know, if it is possible at all to create a 3d-printable propeller, which works with a satisfying efficiency. When successful it would be very useful, because pitch and diameter were freely adjustable, and...
Print your own propellers! The pitch and diameter of these designs are adjustable and can be optimized for the geometry of the propeller and the hub can be tuned for a specific plane.
The basic version of this propeller has a 9 inch diameter and 4 inch pitch. The design allows change to both parameters and the number of blades from two to three. With 4 or more blades the hub diameter needs to increased as well. Blades and hub are separate parts.
