这个玩具可以通过旋转滚轮来解压，也可以手握着转轴按压手部穴位（大部分人都长时间使用手机和电脑）。

此滚轮里面可以安放5mm*2mm的磁铁达到不同的效果（滚动时，磁力可以让滚轮旋转时间更长，让小朋友们体验磁悬浮的神奇，感受3D打印的魅力），每一侧里面放4个（2侧为8个）或8个磁铁（2侧为16个）

我的磁铁是在PDD上购买的，有一定的误差。

*The following English is all from Baidu Translate

This toy can be decompressed by rotating the scroll wheel, or by holding the pivot and pressing the acupoints on the hands (most people use their phones and computers for a long time).
This roller can accommodate 5mm * 2mm magnets to achieve different effects (when rolling, the magnetic force can make the roller rotate for a longer time, allowing children to experience the magic of magnetic levitation and the charm of 3D printing), with 4 magnets (8 on 2 sides) or 8 magnets (16 on 2 sides) placed on each side
My magnet was purchased on PDD and there is a certain margin of error.

下面为4个磁铁摆放位置，8个磁铁在打印时注意有可能会被打印头吸起

The following are the placement positions of 4 magnets, and 8 magnets may be sucked up by the printing head during printing

请在第24层的时候添加暂停来添加磁铁。

Please add a pause on the 24th layer to add magnets.

Below is a physical video

2侧共16颗磁铁的效果

Effect of 16 magnets on 2 sides

2侧共8颗磁铁的效果 当旋转的时候还有自行车棘轮的声音。

The effect of 8 magnets on both sides is that there is still the sound of bicycle ratchets when rotating.
