Extrude Faces for 3d-printer (stl)

Hi at all, with the help of Grasshopper and GeometryGym I got a cube like you can see in the picture. In the moment the cube exists of trimmed surfaces.

Now I want to prepare the cube for a 3D-Printer, and I need a *.stl-file with solids instead of the faces. So I extruded each face along the normale in both directions. But at the interactions of the faces I got these strange overlappings. So I looking for a better methode to get a clean, nice cube with a thickness..

I hope you can help me.

Thank you.

I am not so familiar with stl, but as I can see, it operates on meshes - so why u not use weaverbird ? It has a powerful meshThicken component.

It's not that easy to get uniform wall thickness, but something along the lines of the attached will get you something you can print with neat junctions.

Cheers,
