Need help filling in a part to make it solid

[threedee4me]

not sure what software to use. tried mesh mixer to no avail. i want to take this part and fill in the areas i marked in red to make them solid.

thanks for the help

I would import() it into OpenScad and have a loop that goes 270 degrees adding rectangles ( actually cubes([-,-,-])'s at increasing angles and translations )

If you post the .STL file, I might just do it for you...

thanks!! whats the best way to post the file? dropbox?

Or download Netfab Basic [free] and edit the stl file. Delete the sidewall triangles and use the hole repair tool to add triangles across the remaining gaps.

You can go to the 'Go Advanced' post option and there will be stuff to attache a file to a post. .STL files can be attached.

thanks so much roxy see file attached. i will check out netfab as well csmonkey.

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:

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);
}

thanks so much. not sure how to do what you are saying "yet" do i need that exact version? i found past versions on the site and located that exact one or can i just use the latest version?

what do i do import the stil into the openscad program then input the code above somewhere? then export the file and print?

thanks

Probably any current version of OpenScad will work. But that version is what I used. Just put the input .STL file in the same directory as you create the do_fill.scad program. The .STL should be found by doing that. Then Render it and export it.

very confused. i downloaded the program. not sure what to do next? how do i import the stl and then what do i do past the code above into the editor?
thanks for the direction
