The Fractal Bench Vice, designed based on fractal geometry in mathematics, can effectively grip objects of various shapes.

With fewer support required, the fractal module is print-in-place, significantly simplifying installation compared to other designs. If higher strength is required, the model thickness can be increased and carbon fiber materials can be used.

The Fractal Bench Vice possesses self-similarity and scalability, demonstrating that mathematical concepts can be used to create practical and pleasing designs.

Required components: one 608zz bearing, multiple M3 10mm screws, and M3 12mm screws can be used as partial substitutes.

基于数学中的分形几何学设计的分形台虎钳，可以有效夹住各种形状的物体。仅托盘零件需要较少的支撑，分形结构为一体成型，相比其他方案安装大幅简化。如果需求较高的强度可以增大模型厚度并使用碳纤维耗材。

分形台虎钳具有自相似性和可拓展性，说明数学概念可以用来创建实用且美观的设计。

需要的零件：一个608zz轴承，若干M3*10mm螺丝，M3*12mm螺丝也能部分替代。

Update：

If you have TPU, you can print the new module with better performance. 

If I have time, I'll add new modules to it, so let me know in the comments.

如果你有TPU耗材，可以打印拥有更好性能的新模块。如果我有时间，会添加新的模块进去，可以在评论中告诉我。

Importment Update:

The printing configuration for A1 mini has been updated! Despite shortening the length of the guide rails, the new extension module has actually increased the available area. 

The A1 mini configuration comes with this module. Please let me know if you encounter any printing issues.

适用于A1 mini的打印配置已更新！虽然缩短了导轨长度，但新的延长模块反而增加了可用区域。A1 mini配置中自带该模块，如果打印有问题请告诉我。

The extension module is compatible, so non-A1 mini users can also use this module to obtain a larger available area. 

It is divided into two levels, and the images show that this module significantly extends the area.

延长模块是兼容的，非A1 mini用户也可以使用此模块获得更大的可用区域。延长模块分为两个档位，图片显示该模块的延长效果显著。

The design adopts a modular approach, divided into a base and detachable modules. Among them, the fractal gripping module is print-in-place, which can be printed and assembled directly. As the precision requirement is high, it is recommended to reduce the printing speed and perform flow calibration in advance. The module can be printed separately to increase the success rate.

采用模块化设计，分为台座和可拆卸模块。其中分形夹具模块采用一体成型设计，打印完成后即可活动。对精度要求较高，建议降低打印速度并提前进行流量校准。可以单独打印此模块从而提高成功率。

Embed the 608 bearing into the groove of the slider, and use screws to connect them as a whole.

Then, attach the base plate and fixed blocks, and secure them with screws. The module has reserved holes, allowing for easy installation at any time.

将608轴承嵌入滑块的槽中，使用螺丝将其连接为整体。

之后装上托板和固定块，用螺丝固定。模块预留了孔位，随时可以安装。

The C-type clamp is included, which can be fixed to a table. Insert the slot into the base and secure it with screws, and there are fixed screws at the bottom.

You can add plastic lubricant as needed, I used PETG to print the base, and PLA+ to print the fractal module and screws. This makes it convenient to fix small models in place.

附带C型夹具，可以固定在桌子上。将插槽卡在底座上并用螺丝固定，底部有固定螺栓。

可以看情况加上塑料润滑脂，我使用PETG打印底座，pla+打印分形模块和螺栓。可以方便地固定小模型。

Need it longer? Do like this. However, structural strength will be lost, and reliable extension modules will be updated soon.

需要它更长吗？这样做。但是会损失强度，可靠的延长模块即将更新。
