These cable rails allow you to deal with the “slack” in cables (specially power cables). Print one or two and “wrap” the cable around them.

The “lid” is meant to slide on top of the cables, keeping them in place. It has a simple detent mechanism: slide it in.

They are meant to be used under a desk, but I suspect that with the lids on, they can also work in a vertical multiboard.

Use these bolts to attach them to the board: [https://makerworld.com/en/models/884571#profileId-839400](https://makerworld.com/en/models/884571#profileId-839400) They will allow you to use an allen key to tighten them through the holes in the rails.
