$1 AMS lite lite lite 3元自动续料

This is a low-cost (semi) automatic material renewal solution powered by rubber bands, which can achieve non-stop replacement of consumables, with a low cost of only 3 RMB.

A1/A1 mini and Creality K1C have been tested to be perfect, theoretically supporting all printers, but you may need to make slight adjustments according to the actual situation, so I have provided the source files for your convenience in secondary creation.

The model is divided into pneumatic connector version and direct insertion version. The direct insertion version does not require a pneumatic connector to be directly connected to the PTFE tube, but there is a risk of loosening.

The BOM is placed in the original STL model, including part specifications and links, which you can refer to for purchase.

这是一款使用皮筋动力的低成本（半）自动续料方案，可实现不停机更换耗材，成本低廉仅需3RMB。

拓竹A1 mini、创想三维K1C实测完美，理论上支持所有打印机，但可能需要你根据实际情况微调，所以我提供了源文件方便你二次创作。

模型分为气动接头版和直插版，直插版不需要气动接头直接和四氟管连接，但有松动风险。

BOM放在STL原始模型里，包含零件规格和链接，你可以参考购买。
