Need help filling in a part to make it solid

[Roxy]

Here you go. Put this into OpenScad Version 2015.03-1. I left one line of the debug turned on so you can see how this is done. You can turn the debug off by removing the '#' sign. (however, that should not affect the final .STL file that you export.)

Do a Design/Render And then do a File/Export/.stl You will get this:

fibo_fill.jpg

do_fill();

s = .015;
s2= .061;
s3= .050;
s4= .090;
s5= .090;
s6= .1;

module do_fill() {
    translate([-7,-14,0]) import("fibofidget.stl");

    for(i=[-27:1:250])  
        rotate([0,0,i])    translate([11.1,0,0])  cube( [4.8+i*s,1,4]);    
    
#    for(i=[90:1:250])  
        rotate([0,0,i])    translate([11.1,0,0])  cube( [2+s2*i,1,4]);    
    
    for(i=[120:1:250])  
        rotate([0,0,i])    translate([11.1,0,0])  cube( [4.5+s3*i,1,4]);    
    
    for(i=[0:1:120])  
        rotate([0,0,i+135])    translate([22.1,0,0])  cube( [1.0+s4*i,1,4]);    
    
    for(i=[0:1:90])  
        rotate([0,0,i+150])    translate([24.5,0,0])  cube( [1.0+s5*i,1,4]);    
    
    for(i=[0:1:60])  
        rotate([0,0,i+160])    translate([27.0,0,0])  cube( [.5+s6*i,1,4]);    
    
    translate([-5,-23,0]) scale([.25,1,1]) cylinder(r=8, h=4, $fn=55);
    translate([-8,-30,0]) cylinder(r=3, h=4, $fn=55);
