The Thingiverse file is low-resolution. Check out this high-quality option: http://www.stlhive.com/shop/aviation/propeller-130-x-75-2mm-shaft-3vdc/. Print Settings: Printer: OBJet Rafts: No Supports: Yes Resolution: HIGH as specified Infill: Solid (For mass balance) Notes: Don't print this and spin it too fast unless you have a printer that can handle 150 micron or better. This was printed out of RESIN on an Objet, with excellent results. It has also been printed successfully on a FDM printer with tight support material and some sanding and balancing required. No balancing was needed when printing with the Objet. Please read the .PDF warnings about spinning parts. Post-Printing: Sand Finish Balance How I Designed This: Engineering Education Making the model is challenging, but knowing what to do and what not to do is even harder. Determining and maintaining correct pitch is crucial - also, the airfoil was designed by me!
