p1料盘支架保护套

我在打印东西时发现料盘会和打印机涨紧轮凸出来的螺丝发生剐蹭，后来我设计了一个料盘保护套，可以在料盘和打印机之间增加一段距离有效避免剐蹭，同时还可以保护料盘避免磨损。

I found that the material tray would rub against the screws protruding from the printer's tension wheel when printing. Later, I designed a material tray protective cover that can increase the distance between the material tray and the printer to effectively prevent scratching and also protect the material tray from wear and tear.
