按压升降棉签盒(Press-to-Lift Cotton Swab Storage Box )

一开始我希望可以制作一个每次取出一根棉签并让它竖立起来方便拿取的结构。

后来我发现，棉签的形状决定了它不太可能听话地从一个短小的行程中分离出来单独的一根。

所以我只好把它们放在了一起，当然我们依旧应当为它们提供一个良好的储存空间，以使其尽量保持干燥。

外壳等部分使用了PLA材料，弹簧和连杆使用了PETG。

我尽量让所有的部件可以直接结合而不必依靠胶水或者金属螺丝等物。

这个模型在我手上使用了一周左右的时间，大部分时候都工作良好。

以下是一些需要特别指出的问题:

1. 演示用的盒子高度与盖子不齐平是因为在制作试验品的时候计算失误，提供的模型中已经修改了外壳的高度。
2. 连接杆的部分提供了两种模式，一种是使用了螺纹来方便连接，另一种则没有螺纹。这两种连接方式的潜在问题在安装文件中详细说明。
   默认的15%填充应该是足够使用的， 如果不放心可以使用添加了修改器的文件来打印，打印时长会相应边长。
3. 塑料材质的弹力持久性并不是那么令人放心。可以考虑使用金属弹簧来替代打印的弹簧。已经在底板上预留了位置，也许未来会为模型增加弹簧托板，这样可以更持久的使用。当然即便不使用金属材质的弹簧，在打印件的弹力消失后，也可以再替换一个新的，毕竟打印弹簧只需要约15分钟。
4. 考虑到可能需要更换弹簧，所以底板没有使用胶水或者卡扣固定，我相信底部与盒体的连接足够紧，同时由于这个盒子的使用场景是位于台面上，所以也无需担心底板脱落。(如果脱落了，请按回去。想使用胶水，当然也是可以的。)

Press-to-Lift Cotton Swab Storage Box

At first I hoped to create a structure that would remove one swab at a time and allow it to stand up for easy access.

Then I realized that the shape of the swabs made it unlikely that they would obediently separate from a short stroke.

So I had to put them together, but of course we should still provide a good storage space for them in order to keep them as dry as possible.

PLA was used for the shell and other parts, PETG for the spring and linkage.

I tried to make all the parts fit together directly without having to rely on things like glue or metal screws.

This model took about a week in my hands, and most of the time it worked well.

Here are some issues that need to be specifically noted:

1. The height of the demonstration box is not flush with the lid because of a calculation error when making the prototype. The height of the shell has been modified in the provided model.
2. The part of the connecting rod is provided in two models, one that uses threads to facilitate the connection and the other that has no threads. The potential problems with these two modes of connection are detailed in the installation documentation.
3. The plastic material is not that reassuring in terms of spring durability. Consider using metal springs instead of printed ones. A place has been reserved on the base plate, and perhaps in the future a spring pallet will be added to the model so that it will last longer. Of course even if a metal spring is not used, it can be replaced with a new one after the spring in the print has worn off - after all, it only takes about 15 minutes to print a spring.
4. The durability of the elasticity of plastic materials is not so reassuring. You can consider using a metal spring to replace the printed spring. A position has been reserved on the bottom plate, and maybe a spring support plate will be added to the model in the future, so it can be used more durably. Of course, even if you do not use a metal spring, you can replace it with a new one after the elasticity of the printed part disappears, after all, printing a spring only takes about 15 minutes.
5. Considering that the spring may need to be replaced, the bottom plate is not fixed with glue or snaps. I believe that the connection between the bottom and the box is tight enough, and since the use scene of this box is on the table, there is no need to worry about the bottom falling off. (If it falls off, please press it back. If you want to use glue, of course, it is also possible.)

我之后将会上传这个盒子中用到的锁定机构的演示模型，事实上它是一个经典的机构，也许不值得为它建立一个演示模型，但是我做了，所以就上传。

I will later upload the demonstration model of the locking mechanism used in this model. In fact, it is a classic model, and perhaps it is not worth creating a demonstration model for it, but I did it, so I uploaded it.
