Onward with scaling up. It goes slower than a 2" model since each part goes as a separate page to be printed, scored, and cut separately. I've been looking at the Glowforge for cutting, but I'd prefer using someone else's machine instead of putting out the money to buy one.
I've been putting in one or two parts per day instead of doing all 20 of the parts in at once. Oddly the interior triangle of the subdivision ends up with sides which don't quite reach. I'm not sure why. Every strut section should be the same size.
Clamps seem to be needed in this scale.
Almost done with the structure.
