It's done, but breakable...

Hi there,

Thanks to everybody, I could make my first script things.
It is a Soroban, a Japanese abacus. It worked. But some beads sometimes fly out to the wrong direction.
It might be why I couldn't link them all. So I can never move the whole things.
A vertical lined up beads have each script, but close one. I put one script here. Any advice will be appreciated.
