Have you tried building these without the Bucky Balls inside. They look good, but I think the Bucky Balls might have a bit smaller to get the skins to line up tighter, then there is the paper compound curve problem. Accrued intolerance becomes a big problem when using many parts, especially if they overlap. Some notching of the over lapping straps so they are flush with the frame may cure that. The Cameo will make that quite easy to incorporate. I can't cut with scissors worth a dang, my hands cramp up too much, so take what I post with a grain of salt. Very colorful and eye catching.
The buckyballs are the main feature. In my view. If I'd put the pole axel in correctly the edges of the skin would have align over the stringers, eliminating the accrued intolerance. I like leaving some panels off so that the structure can be seen. I think this is better for showing Fuller's thinking and avoids the problem of having the model indistinguishable from a Styrofoam ball. My original goal was to design a tool for producing fantasy and science fiction maps with detachable panels which can be drawn on freehand and then removed and scanned. For this the alignment of the panels with underlying grid is more important that the fit of the skin. My reasoning for this structure is to produce a spherical grid. Seeing the grid lines between the panels is fine.
I've talked online with a gal setting up presentations and panelists for cons and she was interested, but I've decided I'd rather talk to people one on one in the hallways at cons. It makes for less of a one-sided conversation.
I've found that building these things at sci-fi cons is a great way to get into discussions about Dyson spheres, Buckminster Fuller, astronomy, mathematics, and space ship design. For these purposes the model only needs enough skin panels to communicate that it's the Earth, or whatever planet I want. I've downloaded a map of Pluto.
I also made the mistake with this one of using cardstock as the skin instead of thinner paper. So that leaves me thinking should I go ahead and finish this build or abandon. I think I finish it since mistakes can be interesting.
