foldable map of Ida Options

[chuckclark]

Here is a constant-scale natural boundary map of Ida that folds to a decent replica of the asteroid. Map edges are Ida's major ridges.[attachment=16299:Ida_MaxRidge_post.jpg]
[EDIT] Here it is again with the photomosaic properly credited; apologies to M. Nyrtsov for my oversight.

Okay, so borrowing a little from both systems, here is the csnb map of Ida along with a set of three (only three!) interlocking ribs, one rib for each major axis. The ribs' white lines indicate where slots are to be cut, black lines to remain as assembling guides. (Note that the short rib will go in as two separate pieces.)
DON'T, anyone, at the risk of extreme frustration!, take this plate for anything but a suggestion. I made the rib shapes from Tayfun's ORTHO VIEWS plate, and Ida is so extremely concave that the "short vertical rib" is only a guess for accurate, because its perfect shape is hidden from both directions. It needs some uncertain amount of trimming near point z. Plus, I haven't tried assembling this yet to see if in fact I've got the ribs and the map at the same scale.
BUT, with this as a guide, Tayfun will be able to generate these three ribs easily and accurately; and thickness of slice won't be an issue.

Just to lessen confusion, the ribs shown in Ortho Views are flipped from what is shown in the map plate.

Tayfun, if you'll make them for our asteroid set so far (Eros Ida, Phobos, Deimos), I'll set each in scale with the csnb maps, and trim them in where the folded csnb-form deviates from true shape. (Eros in particular is the troublesome one to hold up shape in hollow folded paper, and probably will need another "short" rib, parallel to the main short rib and centered on shoemaker.)

The assembled result will still be a bit susceptible to dents, but the overall skills required won't be at the level of a professional model builder to get it done.
