This version has been optimised for 3D fdm printing.
In the original version of the mesh, you can see many hexagons connected to each other and the docking posts touch in many places.
The surfaces of the hexagons also showed deformations
In the original, the slicer created real contacts between the columns, whereas in the published version they all remain clearly separated
Then using the Prusa slicer I coloured the hexagons in 6 colours and printed with the IeC 9/12, a 9-colour printer.
The mesh was also decimated in the number of triangles (1/10)
The author remixed this model.
