这是一只为夏天玩水设计的 3D 打印小鱼。

为了发布它我专门带孩子去泡了温泉哈哈哈

它的尾部设计成了水轮结构，当水流经过时，尾巴会被推动旋转。

它适合泳池、浴缸、水盆和亲子玩水场景。

除了好玩，它也可以作为一个简单的水流机械原理小教具，让孩子直观看到“水流如何带动物体运动”。

推荐使用亮色打印，让它在水面上更醒目。你也可以尝试不同颜色组合，做出属于自己的夏日泳池小鱼。

This is a playful 3D printed fish designed for summer water fun.

Instead of making a simple floating fish, I wanted to create a little toy that actually moves in water. The tail is designed as a small water wheel. When water flows through it, the tail wheel spins, making the fish look like it is swimming.

It works great as a pool toy, bath toy, or a simple water-mechanism demo for kids. Print it in bright colors to make it stand out in the water, or try your own color combinations for a fun summer pool party vibe.
