Description
IMPORTANT: The single blade model is designed to be printed out by a 0.4mm nozzle, but you will have to increase the horizontal offset by 0.1mm to be able to print the trailing edge, because the modeled trailing edge is only 0.2mm thick. That is the offset required to get the interlocking hub to work as well.
75mm diameter, ideal for use in ducted quads like the cinewhoop. The was particularly designed with the duct geometry available for the frame provided by Shendrones.
Pay attention to the sample print pictures for optimal single blade print orientation! Suggested layer heigh is 0.08 or 0.12mm. At o.08mm it will take 7 hours to print out a full set of blades.
The blade is thick, and gets its stiffness from the geometry, not that material, so I would suggest printing it in PETG to make it less brittle.
If you need propeller, ducted fan, windmill or contra-rotating stator design help feel free to contact me for your custom aero-design.
