Parametric Propeller & Duct Design - Fusion 360


Hey everyone - I worked with @pacificmeister to create a fully parametric design in Fusion 360 for a propeller and duct combination.

Here’s a video demonstrating how to make changes to the model and how it was built:

You can look at / download the Fusion 360 file here:

The design is certainly not perfect, as the airfoil profiles are really just rough estimates at this point. I tested changing most of the important parameters, and the model doesn’t seem to break. Hopefully this is valuable to everyone else, and at the least a starting off point for other builders!

Hi @Taylor, that’s a great update. So many possibilities now and it’s fantastic to have a corresponding parametric duct now too. I was just experimenting with the duckt profile curves, want to try a less agressive foil profile and test a more parallel droplet shape to see if that works better for higher speeds. I also shrunk the size (riding direction) to reduce drag. I also need to figure out a way to integreate my threaded duckt mount to this new one. I’ll post an update when I have something ready. Thanks! And I am looking forward to others experimenting with this Fusion model too.


I did a quick mod on @Taylor 's setup and made it fit to my threaded system. Really nice that parametric control. I also made the duct thin and fast, NACA0012 foil profile (inspired by @Hiorth). Maybe too fragile for PLA, we will see. It’s printing now. Caution: untested.


Hello pacific master

Do you print your support or all parts on your QIDI TECH X-one printer?
Is the pressure range of 140x140 mm sufficient for this? Or do you submit the print jobs?
I am currently researching which 3D Ducker should be purchased, and your device I like quite well. (if the pressure range is sufficient).

Servus @mac23! Hmm, “pressure range”? Maybe a Google translate thing… ah I got it haha “druck” = print and also pressure. “print volume”. Mine is 150x150x150mm and that’s barely enough. I design everything to fit my printer which limits what I can try, especially on duct and prop.


I love my creality cr-10. They are about $420 Aussie inc shipping. 300x300x400mm and acceptable quality (for my standards.) very well supported online by community. Lots of upgrades etc.


Agree CR10 ftw :+1:

( post has to be 20 letters so that’s why this is here fml lol)


all right. then I will have to look for another model, because the new version of the x one is again 10mm smaller.
I also take a look at the CR 10. Thank you very much for your feedback.


Struggled to print the leading edge of the duct, despite the fact it was sitting up and not on the build plate. Not sure if reversing the orientation and using a lot of suports would help, or it’s just not suitable for PLA print.


Mine printed ok in PLA. Still haven’t tried it and don’t know if it holds. It’s pretty thin/weak compared to my old one. I definitely think i made the struts too flimsy.


Hello Taylor or anybody

I looked at your nice video and downloaded theParametrics PropDuct.igs file but when opening in Fusion360 the Timeline dissapears and there seems to be no parameters to change. What am I doing wrong? Thanks / Jan


Looks like you are not opening a real “Fusion 360 file”.


The file is Parametric Propeller & Duct.igs and it opens with Fusion360



You need .f3d file. I just tried the link at the very top and it works.


You saved my day. I faught with this one for quite a while. /Thanks
