大家好，今天跟大家分享一个减压玩具
鳄鱼电报夹，温馨提示，减压玩具噪音较大，使用时请避免影响到别人。
原作品来源于黑皮哥分享的EDC鳄鱼电报夹，感谢他的分享
在他模型的基础上，做了如下优化
1. 首先原作者使用5mm直径的磁铁，修改为了6mm，厚度为3mm不变。一方面更大的磁铁提供更强的磁力，撞击声音也更清脆。
另一方面降低了对磁铁等级的要求，经过测试，N35等级及以上磁铁便能满足要求。
2. 增加了顶部的钢珠，用4mm钢珠进行镶嵌，增加按压时撞击声音，以下是增加前后对比。
3. 改进中轴，原作者中轴留的余量较大，本次将中轴加粗，并缩短了一些，组合后更加紧致。
4. 增加了一些个性图案，有多色打印的可以挑选多色打印版本。

经过多次打印尝试，分享一下打印设置点。
1. 推荐使用5层墙厚，50%填充打印，层高选择0.15。
2. 如果需要打印图案，建议在切片软件中，将墙生成器由经典改为Arachne，可以切片观察图案是否生成正确。

关于打印后模型的安装
1. 将磁铁分别推入凹槽，整个磁铁与端面齐平即可，注意区分正负极
2. 将夹子合拢，适当按压，保证夹子闭合紧密。
3. 将夹子分开，502胶水少量滴入磁铁缝隙，胶水渗入后，立即擦干表面多余的溢胶。
4. 钢珠孔滴少量胶水，将钢珠放入孔内，等待胶水干燥即可。

最后，本模型全部开源，有需要的可以通过下面网址自行下载。
祝大家玩得愉快，关注我，后续给大家带来更多开源分享。

Hello everyone, today I’m sharing a stress-relieving toy with you: the Crocodile Telegram Clamp. A gentle reminder, this stress-relieving toy can be quite noisy, so please use it considerately to avoid disturbing others.

The original design comes from the EDC Crocodile Telegram Clamp shared by Black Skin Brother. Thank you for his sharing.

Based on his model, I have made the following optimizations:

First, the original designer used 5mm diameter magnets, which I’ve modified to 6mm, with the thickness remaining at 3mm. On one hand, the larger magnet provides stronger magnetic force, and the collision sound is crisper. On the other hand, it reduces the requirement for the magnet grade. Tests have shown that N35 grade and above magnets can meet the requirements.

I’ve added steel balls to the top, using 4mm steel balls for inlay, which increases the collision sound when pressed. Here’s a comparison of before and after the addition.

I’ve improved the central shaft. The original designer left a large margin for the central shaft, so this time I’ve thickened the central shaft and shortened it slightly, making the assembly tighter.

I’ve added some personalized patterns. Those with multi-color printing can choose the multi-color printing version.

After multiple printing attempts, I’d like to share some printing settings:

I recommend using 5-layer wall thickness and 50% infill printing, with a layer height of 0.15.

If you need to print patterns, it is recommended in the slicing software to change the wall generator from classic to Arachne to check if the pattern is generated correctly when slicing.

Regarding the installation of the model after printing:

Push the magnets into the grooves respectively until the entire magnet is flush with the end face, and be careful to distinguish between the north and south poles.

Close the clamp and press it gently to ensure that the clamp closes tightly.

Open the clamp, drop a small amount of 502 glue into the gap between the magnets, and wipe off any excess glue on the surface immediately after it has penetrated.

Drop a small amount of glue into the steel ball hole, place the steel ball in the hole, and wait for the glue to dry.

Finally, this model is completely open-source. Those who are interested can download it from the following URL.

Have fun, and follow me for more open-source shares in the future.
