此盒子需要用到一块100×100×2mm的透明亚克力板，其中4个角需要加工出1mm的倒角，可以用水口钳剪；还需要4颗直径6以内的强力磁铁，可以到淘宝购买。This box requires a 100×100×2mm transparent acrylic board, where the 4 corners need to be chamfered with a 1mm cut, which can be done with a water jet cutter. It also requires four strong magnets with a diameter of up to 6mm, and can be purchased on Amazon.

先打印盘7的磁铁测试件，比如手上的磁铁是直径6的，就打印6那一个测试件。打印出来后，将磁铁依次插入测试孔里，当需要用点力才能插入，插入后又不会轻易掉出来时，记录对应位置前面的数字，即配合值，比如+0.1，那所需要的磁铁孔直径就是6+0.1=6.1（代数A）。将磁铁的实际高度加上0.2安全距离，如实际高度是5mm，则是5.2（代数B）。First print the magnet size test piece for plate 7. For example, if the magnet on your hand is a 6-diameter, print the test piece with a diameter of 6. After printing, insert the magnet into the test hole in order. When it takes a little force to insert it and it does not easily fall out after insertion, record the number in front of the corresponding position, which is the fit value, such as +0.1. The required diameter of the magnet hole is 6+0.1=6.1 (algebra A). Add 0.2 safety distance to the actual height of the magnet. If the actual height is 5mm, it is 5.2 (algebra B).

将盘1和盘2的各两个负体积圆柱的尺寸都修改为上面计算出来的值（X=Y=A，Z=B）。然后点移动，将负体积圆柱的Z坐标值改成如下图的计算值。Modify the dimensions of the two negative volume cylinders on plate 1 and plate 2 to the values calculated above (X=Y=A, Z=B). Then click Move to change the Z position of the negative volume cylinders to the calculated values shown in the image below.

开始打印，在暂停时，放入磁铁或亚克力板，之后继续打印。注意：在放磁铁时要区分方向，确保上下盖盖一起时能相互吸住；放亚克力板时，需要在板的边缘涂上一点固体胶（涂胶面朝上），以便在后续打印时耗材丝能顺利地粘在亚克力板上。Start 3D printing, and when paused, place 2 magnets or acrylic board, and then continue printing. Note: When placing the magnets, distinguish the direction to ensure that the upper and lower covers can be attracted to each other when they are placed together; When placing the acrylic board, it is necessary to apply a bit of solid adhesive on the edge of the board (with the adhesive surface facing upwards) so that the consumable wire can smoothly adhere to the acrylic board during subsequent printing.

上下盖之间的转轴可以直接用耗材丝。The rotating shaft between the Top Cover and Bottom Covers can be made of filament.
