windmill blades.
Hi,
I'm trying to 3D print a model of a windmill. The blades will
eventually be bigger than my printer can handle, so I'll have to chop
them up into printable parts. I was planning on making
the mating constructions in openscad.
Now I've downloaded a windmill blade model from thingiverse:
https://www.thingiverse.com/thing:2122925
and it renders just fine as long as I don't add or subtract anything
from it.
For a first test I just want to print it scaled so that it fits on my
printer:
module blade ()
{
translate ([3,13,95.5])
rotate ([90,0,0]) import ("bird_blade/Bird-Blade.STL", convexity = 10);
}
blade ();
*cylinder (d=50, h=1.1);
once I add the cylinder (to fix it to the bed), a "render" will
complain it is not closed and remove the blade from the render.
I've seemingly tried 6 windmill blade models, and all of them
have this problem.

wind_turbine/source:https://www.thingiverse.com/thing:1252692
I've run all of them through an online STL fixer and they still
have this problem.
Does anybody have a suggestion on how to get this working ?
Roger.

f equals m times a. When your f is steady, and your m is going down
your a is going up. -- Chris Hadfield about flying up the space shuttle.
Looking at the first one in NetFabb studio it isn't a closed mesh. It has
holes and self intersections so I expect the others are all the same. I
don't think OpenSCAD is ever wrong when it calls out STLs. Most STLs on
Thingiverse are broken.

Have you tried grouping the objects in Cura?
