仓鼠打碟玩具最近网上挺火的，打印好（可以设置多色），销轴从一遍插入（有一边孔大一点）就装好了，销轴的平面一边朝下，方便滚动。

The hamster disc toy has been quite popular online recently. After printing (multiple colors can be set), the pin shaft can be inserted once (with a slightly larger hole on one side) and installed. The flat side of the pin shaft is facing downwards, making it easy to roll.
