Hi
Thank you so much. Could you add some feature to your model to improve it? such ac adding guide vanes (fixed and variable) , end plate , a ring around the blades and finally another row of blades (2 or 3 rows of blades, biplane wells turbine)
Thanks a lot for your precious work
best wishes

I provided the code. So you can download it and adopt it to your needs.

It works with me. Might be a syntax problem. Check the brackets, check the expression.
All I changed is the line

translate([0, 0, ch/2+1])

into

translate([0, 0, -(ch/2+1)])

If you don't get it work, please contact me directly using the email address shown at the end in my youtube films and attach your code.

best

best regards,

Great design and easy to use file for the Openscad. Im impressed about your other work with turbines and wave energy plants.
Im planning getting one printed to use for a engineering school project but I have never tried to work with Openscad and is stock with a problem in your scad file. I have to make the rotor in half in order to print it - but I'm only able to get the bottom part of the rotor when typing following in the scad file :
// half print

half = true ;

I don't know what command to type in order to get the top part of the rotor ?
I've tried to search the internet but without any solutions.. I would really appreciate your help.

Yours sincerely,
Magnus

sorry for that.
Solution: Just put a minus sign into the z-translation of the cube

....

if (half)
{
difference(){
turbine(naca, blades, depth, D, d, cd, ch);
translate([0, 0, -(ch/2+1)])
cube([D+1, D+1, ch+2], center = true);
}
}

I've tried to insert your solution in the scad file but when compiling - nothing shows up then. .. ?
