设计的比例是刚好能放入100元的纸币，如果有朋友觉得整体太大了，可以按比例缩小，但是因为我预留的磁铁孔是6mm x 2mm，那我就建议缩小一半打印，这样磁铁孔就会变成3mm x 1mm。于问号部分，不同耗材误差不同，有些耗材可能无法干好插入，大家可以使用胶水将他们粘在一起。

The ratio of the design is just enough to put in 100 yuan bills, if some friends think the whole is too big, can be scaled down, but because I reserved the magnet hole is 6mm x 2mm, then I suggest to reduce the print by half, so that the magnet hole will become 3mm x 1mm. in the question mark part, different consumables error is different, some consumables may not be able to dry and inserted well, you can use the glue to glue them together. together.
