Misumi extrusion 1515 wiring clip

This is a clip to hold in wires along 15mm x 15mm aluminum extrusions. The first one I made of sheet metal and kept hitting my knuckles on it. So I went to plastic as soon as I had the printer running. I made this for Misumi but it should work for others like Openbeam's 15x15. One has a relief for overflowing grove, like my main wiring harness.
