Arknights Pass/Transit/Campus Card Holder

Use four M3*12 cylindrical head screws and matching nuts

(Using M3*10 might also work, as there was about 1.5mm of clearance left)

The model is divided into upper and lower layers. The lower layer needs supports removed. Insert the transit card into the lower layer and the access pass into the upper layer

Both official and self-printed passes have been tried and can be inserted. The resistance might be high, so some attempts may be needed

It is not recommended to use overly rare access passes

This model was inspired by https://makerworld.com.cn/zh/models/1505947-ming-ri-fang-zhou-tong-xing-zheng-qia-tao-gong-jia?appSharePlatform=copy#profileId-1644459 but was modeled by me from scratch

I have been using this intensely for a month, and this thickness actually has no effect on card swiping. A minor discomfort is that the exposed screw parts have sharp edges, which need to be sanded down
