3.3 DESIGN DEVELOPMENT + FABRICATION OF PROTOTYPE V.3 In 2.0 Design, the pivoting edge of the bone structure were initially connected by using wire to spiral over, however as it gave a rough finish, we looked for varies sizes rings to substitute the wire spiral. We begin trying with smaller rings (12mm diameter), but when the panels fan out, the mouth of rings tear apart, so we worked on several larger ones.
12mm diamter ring, sprayed black
17mm double loop ring splited
12mm diameter ring
19mm single ring

For the various ring sizes that we looked up are basically metal rings, such that we have tried to spray them black in coherent with our design. Yet, the finish is again rough, and the paint peels off easily on the smooth surface of metal rings, hence we decided to remain the original look of the metal rings instead.
