A simple TPU light shield for the Surface Pro X charging cable to block the bright LED at night.

The part is meant to be 3D printed in TPU, allowing it to be easily slipped over the charging cable without disconnecting or modifying the cable in any way.
Thanks to the flexibility of TPU, the cover fits snugly and stays in place while still being removable.

This is a purely passive solution – no electronics, no glue, no permanent changes.
