Re: 3D TOS Shuttlecraft...
Seeing this take form from scratch one can quickly appreciate that this design is far from being a simple boxy shape. Actually it's quite impressive that they built such a thing as a full-size mock-up and it differed very little from what I'm making here. It's certainly far more complex than anything similar TNG ever did in terms of shuttlecraft mock-ups.
