19" rack cable management replacement part

This is a replacement part for cable management panels. The panels I had did have five square holes almost 12mm × 12mm. There were plastic parts inside these holes but the plastic was ancient and crumbled while trying to use them.

To fix the replacement part in place, you can use a M3 screw from the backside (one is enough).

You may need to set xy compensation to 0.1.
