Holders for Eclipse's Hexes

Why ?
------

When playing Eclipse, especially at the beginning of the game and when using extension for 7+ players, it is difficult to maintain the relative positions of the hexes so I planed to make an holder.

Incomplete net:

Note that this thing isn't conceived to make a plain net : it is impossible to make an net without holes due to the conception of the elements. Each element has 4 segments that cover 5 intersections: 3 between 2 segments and 2 at the end of a segment. In the full net each intersection has 3 segments that converge. So each elements bring 3 intersections that need one more segment to be completed but only 2 end that can fill them. All intersection will not be full so the net itself will not be complete but it isn't a real trouble as it only need to be complete enough to hold de hexes.

As long as the system is solid enough to hold the hexes in place, having a incomplete net is convenient because it save some material, place and print-tim
