A card plug the hole of eSun Printing Consumables Boxes

I have a 3D printer, so I have many boxes for consumables, especially the eSUNDE brand. I want to recycle these boxes for tools and accessories, but they all have a hole for observing the color of consumables, which is very frustrating. So I made a brand to plug this hole.

Use Tuozhu X1C printing, with and without logo versions, using default parameters.

Usage: First, insert the wider protruding part of the back into one side of the box, and push it firmly to the end to press the skirt edge of the other side of the card into the hole.

Finally, push the card towards the end in this direction to make the box watertight.

我有一台3D打印机，所以我有很多耗材的盒子，特别是eSUNDE 品牌。我想循环利用这些盒子来装工具和配件，但这些盒子都有一个洞用于观察耗材的颜色让人很苦恼。所以我做了这么一个牌子用来堵上这个洞。
使用拓竹X1C打印，有有logo的版本和无logo的版本，使用默认参数。
使用方法：先将背部突出较宽的部分卡进盒子的一边，并用力推到尽头，就可将卡片的另一边的裙边按进洞里。
最后将卡片往这个方向推到尽头，就能使盒子变得滴水不漏了。
