Description
Prototype of a variable-area nozzle for use on EDF RC airplanes.
More info about the original build can be found here: https://imgur.com/a/Njsps6G.
Keep in mind this is a prototype meant for testing the basic design, and as such it lacks features such as mounting points and appropriate attachments for the servo rods (the ones present at the moment are probably too weak).
Before printing, please take some time to read my notes in the print settings section.
In addition to the STLs, I've uploaded the original Fusion 360 file for those wishing to modify the design. If you're one of them, a couple of useful tips can be found below.
Edit: following VV3sl3y's suggestion I uploaded a taller version of the inner ring. This one has a longer threaded section in order to enable greater expansion of the nozzle's flaps.
