I'm sure you pushed the envelope, just would really love to hear where most of that weight went

Nice work, Like the design!
it's less dense than aluminum, but it's used in thicker (and larger pieces) usually. Most of the structural tubing on our robots is 1/16" wall thickness, occasionally 1/8". 1/2" polycarbonate is substantially heavier, while still being less dense.
