8040 Propeller Optimized for Printing, V1.0
by Landru, published
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: 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.

Prop came out really nice, cant test them yet because i am still waiting on my motors and other parts from HK. Will definitely post on them.
Thanks for the files

The propeller will need support material enabled.
I highly encourage printing this from PLA, since the thermal contraction of ABS will often warp/crack the blades.
Once printed, remove the support, ream the hole to 13/64", and sand the edges a bit to remove any leftover support or jagged edges.
I've spun this up on a 1300KV hextronic 24g brushless outrunner with a 2S lipo and it puts out some pretty impressive thrust. The propeller feels every bit as strong and durable as a bought one (Though I have not crashed it yet)
I've uploaded a few different orientations as well as CW/CCW Pairs for easy printing.
