I am seeking to fashion this section in order that I will three-D print a changed model of it. I understand how to do very fundamental modeling however I have no idea the place to even get started with modeling this.

I’ve virtual calipers so I will measure the size however I am not positive as it should be measure the curves. After I determine that out, there is not any flat surfaces to even get started a cartoon from.

What would your procedure be for modeling one thing like this? I can be the usage of Alibre Atom3D.

Thank you!
