According to @XiaolongBianBaimahttps://makerworld.com.cn/zh/models/294702?from=search#profileId-223122The exterior shell of this was modified using slicing software, but I don’t have 5mm*2mm magnets on hand—only 9mm*3mm ones. Since I wasn’t familiar with the magnet placement holes, I made them shallower; well, it’s fine as it is... Let the magnets protrude a bit if they have to. Those who need it can modify it further on their own.
