Completed low-poly model.
I think I have just about everything now. Hinge, back ring, shackle, pin, I’m also considering adding support for the bolt system too (last picture shows the shackle with a pair of short bolts).
This going to require some snowflake code I wager, so I’m not 100% sure that I will add that part.
I guess it’s time to unwrap all of this…
