在宜家购买的置物架，宽度只有19.5cm。我想把AMS放上去，所以设计修改了这个支架。

你最好有4组M5*35mm杆径6mm的对锁螺丝，以便牢固的把支架和置物架固定在一起。也可以用自攻螺丝直接固定。

注意：模型使用了负零件来实现螺丝孔。负零件会在使用模型“分离”的功能时消失，我认为这算是一个软件BUG。

若我不提前组合好，又担心下载的人不会组合导致螺丝孔无法正常打印。

The shelf I purchased from IKEA has a width of only 19.5cm. I want to place AMS on it, so I've modified the bracket design accordingly.

It's advisable to have four sets of M5*35mm screws with a diameter of 6mm, along with locking nuts, to securely fasten the bracket and shelf together. Alternatively, you can use self-tapping screws for direct fixation.

Note: The model uses negative parts to create screw holes. Negative parts disappear when using the model's "Split" functions, which I consider to be a software bug. If I don't pre-assemble it, I'm concerned that those who download it may not assemble it correctly, resulting in the screw holes not printing properly.
