The FreeCAD file is included to make it easier to fine tune the parameters.
The original spring was way too weak to turn the propellers. I decreased the number of turns and increased the thickness and growth to make this part stronger while keeping it within the original gear box.
Printed with Maertz Budget PLA Pro. I increased the extrusion rate by ~5% to ensure that it does not break apart between the lines of a layer.
