It is recommended to use a 0.2mm nozzle for printing, as it provides a closer fit when assembling. If a 0.4mm nozzle is used, there may be slight looseness in the assembly. The number of each item can be adjusted on the printing page according to requirements.

建议使用0.2mm喷嘴打印，拼接较为贴合，如果使用0.4mm喷嘴打印可能会出现拼接略微松动情况，可根据需要在打印页面增减每个号码数量。
