The original human nose model (STL) cannot be converted to a solid (in FreeCAD) as:

• The mesh contains two meshes: A big nose outside, and a smaller one inside (not visible)
• The smaller one has holes in the mesh (not tight)

I split and repaired them (using MeshLab) and provide here those both meshes separately. Additionally I created .STEP files from those two meshes (allows to be directly imported as a solid into FreeCAD). STEP files updated (refined) on 6.10.2024.

Thanks to THop3D for sharing the model!
