钢琴黑白琴键造型的壁挂挂钩，针对3d打印进行了优化，无需支撑，且易于安装。
The wall hanging hook with black and white piano keys, optimized for 3D printing, no support and is easy to install

安装指引（Installation Guidelines）：
1.将所有琴键按照图示排列好
All piano keys are arranged according to the diagram

2.将琴键滑入对应卡槽，摆好黑键，推动黑轴，使其穿过所有琴键的圆孔，直到另一端也卡入底座
Slide the piano keys into the corresponding slots and position the black keys properly
Push the black shaft through the circular holes of all keys until the other end also clicks into the base

3.安装完成，按压黑键底部即可弹起挂钩
Installation completed, press the black button at the bottom to pop up the hook

为了适应大多数人的打印机，我将公差设置为0.2mm，如果你觉得安装后黑色琴键太松了，可以自行调整外轮廓补偿，或者按照下面的图片，在白色琴键和底座接触的地方滴入胶水。

In order to accommodate most people's printers, I have set the tolerance to 0.2mm. If you feel that the black keys are too loose after installation, you can adjust the outer contour compensation by yourself, or drop glue at the contact area between the white keys and the base according to the picture below.

希望你们能喜欢！
I hope you like it!

最后，别让打印机歇着。
Finally, don't let the printer rest
