会转尾巴的水轮小鱼丨夏日泳池玩具儿童泡澡玩具水动力教具

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.

 

建议分件打印后组装，方便做多色效果。
尾部水轮需要保持可转动，组装时不要粘死。
水轮轴位建议检查间隙，避免打印误差导致卡住。
推荐使用 PLA / PETG 打印。
如果用于水中玩耍，建议打印后确认所有活动部件顺畅。
小零件不建议给低龄儿童单独使用，需成人陪同。

 

Print the parts separately for easier color changes.
Keep the tail wheel free-spinning; do not glue the moving part.
Check the axle clearance before assembly to avoid friction.
PLA or PETG is recommended.
Make sure all moving parts spin smoothly before using it in water.
