RC plane two, three and zero blade propeller spinner - clockwise and counter-clockwise

thingiverse

This adaptation of Aero330's spinner makes use of his lovely tongue and groove method of aligning the parts, but gets rid of the open slot for the screws that I could never get on with. The tiny screws always fell inside the spinner before I could get them started in the locating holes. This design moves the screw holes to the outside rim of the spinner making a cleaner end result. There's a clockwise and counter-clockwise version for twin engined planes. The usual one to print would, of course, be the counter-clockwise one. March 2018 I've now added three bladed versions and a no blade version. Because the original CAD files were pretty hacked about, the three blade and zero blade versions have been remodelled - three bladed in Sketchup and zero blade in Fusion 360 (which I'm choosing as my modelling software of choice these days). I'll sort them all out and clean them up in time. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2mm Infill: 40% Notes: Once printed, pop the two parts together and using the holes as guides, drill 1mm holes through the tongue. Use the screws that come with servos to fasten the parts together once they are on the prop shaft. Post-Printing A suggested improvement Paint the spinner with acetone to fix the layers together more firmly. The spinner is only thin and you can crush it easily whilst assembling it. How I Designed This I used the Curviloft plugin in Sketchup to repair the original screw holes in the spinner.
