Why is my body invalid?

Hey, like the title suggest, I wanted to ask why my body (video below) is invalid when I try to export it. I am new to Shapr3D and can‘t seem to understand why.

The problem are the „pipes“ when I remove them I can export the body perfectly, but with them it is an invalid body.

Thanks! And sorry for maybe my bad english


What format are you trying to export the body to that makes it invalid? Also, could you be any chance share your design exported in a .shapr format if that works?
