Using fewer mesh lines, 3D graphics

    I want to make the Final use fewer mesh lines,      the ideal version will look like the second image.     Where the triangle shape is more clear and clean. Can anyone give me some advice on how to fix my code?  

ex1 = ParametricPlot3D[{(3 + Cos[v]) Cos[u], (3 + Cos[v]) Sin[u], Sin[v]}, {u, 0, 2 Pi}, {v, 0, 2 Pi}, Boxed -> False, Axes -> False]

mesh = Import[Export[NotebookDirectory[] <> "ex1.stl", ex1]]

edges = MeshPrimitives[mesh, 1]

Final = Graphics3D[Map[Tube[#, .05] &, edges[[All, 1]]],Boxed -> False]
