We didn't use because the T-slot aluminum seemed so good. We also saved a bunch of weight. It is hugely flexible (adjustable) for things that you don't know exactly where they're going to go.

BUT... our frame was not as impact resistant as with the kitbot we used last year. The T-slot fasteners don't handle shock that well. 20mm T-slot is not as bend-resistant as it seems.

For next year, we'll probably use the kitbot for the lower part of the frame, and T-slot for the upper part. Or maybe hand-laid fiberglass-epoxy. Or machine it out of a solid block of titanium...
