Need to add 4cm to middle of tube

[Nomad6666 0]

I have a tube it has threads on each end so if I just stretch it it also stretches the threads not what I want..

Is their a way to to stretch just the center of the tube 4cm leaving the ends with working threads...

if not with Cura what else can I try to do it in?

  

Thanks Bill

Cura doesn't have this sort of function, it's for printing models, not editing them.

 

Ideally you would do it in whatever program was used to create the model in the first place, using the original file from that. There's not a lot of programs around designed for editing STL files, especially in this sort of way.

 

On Windows you could use Microsoft 3D Builder to cut a section of the tube out, duplicate it and put it back together.

 

On other platforms (and Windows) FreeCAD can do it, but it's not exactly beginner friendly. OpenSCAD can do it, but how beginner friendly it is depends on your knowledge of C-style code formatting (it'd be my choice, but I've got a lot of experience with it which is why).

@Nomad6666 It depends on what type of file you have.

 

For editing .stl files, I would recommend looking into Blender. It might take a minute to learn but it's well spent time imo..

While I appreciate you trying to help, I don't think Blender is the best tool for the job here. It's not designed for producing models to be 3D printed (you can definitely make them, but I've also seen some impressively bad files that have come out of it). And for this model (a tube with screw threads on it) a CAD program is far more suitable than a mesh based editor like Blender.

@Slashee_the_Cow Well i completely disagree. Blender has a fine toolkit for editing meshes (wich stl files are). It also has a 3d printing toolkit that you can use to analyze and repair models. The quality of the output depends 100% on the user rather than the program.

Please lets not make this a debate about Blender that is not productive.

@Dustin Assuming that threadstarters file is an stl file, what would you recommend for editing it? 🙃

I dont make recommendations like that, discussion is fine.
But senseless arguing like above is pointless here.
