8040 Propeller Optimized for Printing, V1.0

This is a redesign for an 8040 printable propeller with a 5.5mm (13/64") bore. This prop was designed to keep the minimum cross section above .8mm allowing it to be more easily printed, though at a small efficiency loss. The propeller will require support on one edge, which makes it very easy to remove. I can redesign this for some different center hole diameters if requested, just give me some time as I am pretty busy. Here is a short video with the prop on a motor: http://www.youtube.com/watch?v=v6yClT12Ges&feature=plcp I will also be uploading a 5030 prop once it is flight tested. I printed mine on a Fablicator using Kisslicer.
