Legrand "bubbly" powerstrip bracket

I wanted to attach my “extra thin” legrand power extension (this kind : https://www.amazon.fr/Legrand-049484-049484-Rallonge-Multiprise-Extra-Plate/dp/B09D9WPBCQ ) to my desk, but could not find a bracket that hold it still. This is the result. Printed in PLA, needs supports, holds quite well. Available in smaller form. This version can be printed on the A1 mini as well!
