Cable Opening Edge

The openings I cut in the back of my shelf are less than lovely. So I designed this edge to snap into place. It gives things a more professional look.

This is made for an opening that may be a non-standard size. I took a small container from one of my supply boxes, put it up-side-down on the surface I wanted the hole, and drew around the out edge with a pencil.

Then I cut out the holes! My cuts were not perfectly straight. But I designed and printed this little item and it hides my mistak
