[Gmsh] problem importing stl mesh

[blubee blubeeme]

Hello gmsh community

I am trying to import a .stl file to create hexahedra or quadrilateral
based mesh to use in dealii simulations.

I created a simple model, attached.

How do I convert from .stl to a quad mesh?

When I click mesh->3D I get this error:
Info    : Meshing 1D...
Info    : Done meshing 1D (6e-06 s)
Info    : Meshing 2D...

How can I create a quad mesh from the attached .stl file?
