I’ve played a bit with some interesting modeling methods I discovered during my break.

The idea of this collar is that it’s going to use threaded bolts instead of padlocks for locking, and it is constructed in such a way that you have to “lock” it to get a leash ring (the ring is attached to the mending plate on front) and unlocking it will effectively get rid of that ring. Quirky, I know.

• Picture 1 was the initial design but I’ve widened the edges and made them a bit more rounded.
• Pictures 4-5-6 show how it looks unlocked, partially and fully bolted.
