Paper bag pen bucket simulation

修改自Taco Bell Bag Vase Mode这个模型，因为最开始用这个打印出来结果不太满意，将其导入到3D软件中进行了内部的建模和修改，使得可以更结实耐用，并且可以缩放至A1 Mini也可以打印的大小，不过缩小打印的细节瑕疵暴露比较多，后续会再调整优化。希望你们喜欢~

Modified the model from Taco Bell Bag Vase Mode. Because the result of printing with this model was not satisfactory at the beginning, I imported it into 3D software for internal modeling and modification, so that it can be more durable, and can be scaled to the size that can also be printed by A1 Mini. However, the details of the reduced printing are exposed more flaws, and will be adjusted and optimized in the future. I hope you like it！
