Fiddler crab
Fiddler crabs are a kind of crab with interesting shapes. The male crab has a huge claw. Some of the big claws of fiddler crabs grow on the left and some grow on the right. It uses its giant claws for fighting and courtship.
When a fiddler crab cleans its large claws with its small claws, it's like playing the violin. It lives up to its "fiddler crab" name.
This fiddler crab can be printed in one piece and has multiple joints. The joints designed in this work are different from the common "chain connection" joints. The joints of the fiddler crab have appropriate friction, so they can easily pose in various natural poses.
I like this work very much, I think it is my breakthrough in designing movable joints.

招潮蟹
招潮蟹是一種造型有趣的蟹類，雄蟹擁有一支巨大的螯，大螯有些長在左邊，有些長在右邊。招潮蟹會用巨大的螯來打鬥和求偶。
當招潮蟹以小螯清潔大螯的時候，動作就像在拉小提琴一樣。完全合乎了牠的"提琴手蟹"的別名。
這隻招潮蟹是一個一體成形列印，又具有多關節的可動作品。這個作品所設計的關節與常見了"鍊接"方式的關節不同，招潮蟹的關節有適當的摩擦力，因此能輕易擺出各種自然的姿態。
我很喜歡這個作品，我覺得是我在設計可動關節的突破。
