Not sure that I understand your question. Can you try rephrase it for me please?

If you are referring to a 3d printing post I did a while back, that's done in Blender, with the slicing happening in Cura.
Hope that helps :)

Oh okay....ywah wanted to know the 3d modelling software

Blender is free and absolutely amazing. It's quite a learning curve but there are many videos / articles online as well.
