Mặt dây chuyền rùa Ying Yang độc đáo

I took the idea of this turtle form a nice necklace I used to have and now its gone so I designed it from an old picture.

Designed using open source tools.

No need for supports, works great as a key chain as well.
 
_40 is scaled 40% from my original design
_31 is scaled 31%, this is what I use on the key-chain

I hope you like it, please post your makes.
