最近我找到一个便宜的3d打印耗材，品牌是BING3D材质是PETG-LS.一卷耗材只要￥28.但是耗材的卷轴不能很好的卡在AMS LITE上，老是要掉下来。设计了一个适配器解决问题.

I recently found a cost-effective 3D printing filament. The brand is BING3D, and the material is PETG-LS. A roll costs only ¥28. However, the spool doesn't fit well on my AMS LITE, and it keeps falling off. I designed a holder to solve this problem.

If you're using BING3D filament spools with a larger hole, they may not fit with the A1 Mini AMS Lite. I've created an adapter that allows you to use all my BING3D filament spools with it
