功能：本托盘可存放12堆每堆10枚的1元硬币（仅支持第四版以及之前的1元硬币，也即25mm直径的1元硬币）。上下的边缘被设计为了可啮合的结构，可堆叠存放。

优势：本模型采用水滴型悬垂和倒角设计使其无需任何支撑即可打印，比起需要支撑的类似设计可节约一些打印耗材并且可避免支撑接触导致的粗糙表面。

Description: This tray is designed to hold 12 stacks of 10 1 Yuan coins each (compatible with 4th edition and earlier 1 Yuan coins, which have a 25mm diameter). The top and bottom edges feature interlocking structures, allowing for convenient stacking and storage.

Advantages: This model utilizes a water-drop shaped overhang and chamfered edges, enabling it to be printed without any supports. Compared to similar designs that require supports, this approach saves on printing material and avoids rough surfaces caused by support contact.
