Magnetic Corner Protector

Edit #1: Did a small rework with higher mesh-density.

Edit #2: When printed the bottom did not turn out perfect but when finishing with some fine sand-paper this is okay for me. I sunk the magnets some millimeters and placed felt-tape on top so they won't scratch the grill surface.

I needed a quick and dirty corner protector for my gas grill since the corners of the side-tables start to wear through the cover.
The design is done in OpenSCAD since you might use other magnets (6x3mm) than I do. Variable clearance gives you a bit room for glue. Once I printed four of them I will add photos.
