This is a facial massage roller used to eliminate edema, improve facial fat, etc. I'm too lazy to go out and buy, so I designed this model myself. This model can be printed vertically without additional support and is easy to assemble.

这是一种面部按摩滚轮，用于消除水肿，改善面部脂肪等。我懒得出去买，所以我自己设计了这个模型。该模型可以垂直打印，无需额外的支撑，并且易于组装。
