加长快门

我在使用原模型的时候，由于我的手指有点短，导致快门不是很舒适，而且侧边的悬垂导致我的打印成功率大大降低，我加长了快门长度并且取消了两侧的悬垂。

When using the original model, my fingers were a bit short, which made the shutter not very comfortable, and the overhang on the side greatly reduced my printing success rate. I extended the shutter length and removed the overhang on both sides.
