About this 3D model

原作的很薄很容易损坏，所以做了个更厚实的，封住了底面避免细碎掉落，并且填补了到机械机构的缝隙避免废料飞出。 The original was thin and easily damaged, so a thicker one was made, sealing the bottom to prevent fine pieces from falling, and filling in the gaps to the mechanical mechanism to prevent waste from flying out. 更新update（2024/2/1） 优化入口处，修改为斜面，降低为2层墙，15%填充，可以更快的打印 optimize the entrance，modified to bevel，2 walls, 15% infill， faster printing
