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?Quote:

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.Quote:

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:
Attachment 9820
Code: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
Install it so it can run on your machine????Quote:

To proceed, you would make a source file called do_fill.scad in some directory. Put that code into the file do_fill.scad. Put the original .STL file (with the correct name of fibofidget.stl) in the same directory. Double click on the do_fill.scad file from within Windows Explorer. That will bring up OpenScad. You should see an initial rendering of the output at that point.
sorry to be so clueless. again i am lost. i finally got the code in and i cut and paste it in and saved as i get this which isnt the complete file for some reasonQuote:

also what do you mean by this : Put the original .STL file (with the correct name of fibofidget.stl) in the same directory.
finally did you recode the model or did you somewhow import the file i posted into openscad then fill it in? again sort of lost.
THANKS!
Complicated if you don't have any experience with OpenScad. Magics or the free version of Netfab makes this a much simpler job. Visual editing of the STL is a lot simpler for people not used to CAD.
In Netfab, highlight the inner sidewall triangles and delete them, then use the hole repair tool to cover the planar holes you have created. 2 minute job...
Rich
did not know you could use the loop command without curly brackets. Thanks - learn something new every day.
I'd just combined the original with a shape that filled the holes.
Same basic thing I guess, mine would just have been less elegant :-)
Yours is cleverer lol
not sure how do to this either. where do i go in setting that allows me to highlight the inner sidewall triangles and delete them?Quote:

In Netfab, right click on the part name in the right hand editor tree and go through the menu to the repair section.
In your modeller window the repair options appear above the model on the toolbar, things like select triangle/face/shell. Manually delete/add to edit the geometry.
Don't forget to apply the repair when finished to return to the model window.

total newbie here to cad so bare with me. you did want to try to teach me something. i am open to that but when i cut and pasted the code it didnt come out like the pic you attached it wasnt the full file. if there is an easy way i am open to learning. how do i get the file to look like this
http://i.imgur.com/eyf9I9l.jpg
from the code you supplied?
thanks and thanks for creating the stl.
Yes... That .STL file I just posted is from the code posted earlier.Quote:

Take the .STL file you attached to this thread and put it into the same directory as where the source code for the .SCAD script is located.
Then either change the name of the .STL file to be fibofidget.stl or change the name given to the import() function. The two names need to be the same. And then you will get the correct image. If you just make the .SCAD program be this code initially, you will see if it is finding and loading the .STL file. If you can't get the .STL file to load, it doesn't make sense to make modifications to it.
Code:do_fill();
module do_fill() {
translate([-7,-14,0]) import("fibofidget.stl");
}
Thanks so much for your help and time it is very much appreciated. i will play around with it.
i jus dont get it. i need to take a hands on class. thanks!
I would recommend getting to know at least one good 3D cad package. Blender is good if your altering files in this way but its a bit complex so you might want to go with something easier. Tinkercad is really easy to use, you could probably just import the shape and then drop in a few cubes to fill the holes.
Good luck
Mike
You have a gift for 'under statement'. I've use Blender for a few things that nothing else could handle. But Geeeeeze! That program is hard to wrap your mind around. I'm sure if I used it everyday it would get easier and easier. But right now... It is really hard to use. (But for sure... I've done things with it that no other tool could handle!!!!)Quote:

Another thing is that Youtube can guide you through most actions in Blender so you dont need to spend days learning it if you only have a specific task in mind.Quote:

thanks again
There is a really good Blender course on a website called Udemy. It was a kickstarter and I backed it and followed the course.
It's not a live course but then it's only 195 Euro for 276 lessons. A link to it is lower down this post.
I think you need to be realistic in what kind of instruction you are going to get, live instruction is going to be expensive if you can find it. I haven't seen this kind of instruction.
Most of the knowledge is out there on the internet for free for anyone who wants to learn it. You either want to learn so you put the effort in or you dont really want to learn. If thats the case then Tinkercad or something on that level will be as far as you can go.
Sorry to be harsh but it's the reality of it. Blender is one of the best packages available at the moment and it doesnt cost a penny. Put in a few evenings a week and after a month you will be able to use it on a basic level. The more you learn then the less you need to go back to youtube for help.

hello there can you please tell me about that this blender course still available on Udemy or not?Quote:
