Multi Purpose U Rail

This is a multi-purpose U-Rail designed to be installed under a shelf for supporting rods, bars, or any straight item.
The dimensions are 10 cm (length) × 3.2 cm (base) × 3.0 cm (sides).

The mounting screws are hidden thanks to a built-in housing for conical screw heads. Each hole is slightly oversized, allowing you to easily position the screw before tightening it securely in place.

I originally designed and used this for installing IKEA Goodmorning lights, but it can be used in many other ways as well.

As this is my first shared design, I would really appreciate your feedback and suggestions!
