I needed a quick wrench that I can use to hold an aluminum rod with a 7/16 fastener that would not damage it. 

Print settings are probably overkill but I am using it told hold the rod in place while applying 106 lb-in and it holds well. Does not flex much if at all. Jaws are a bit bigger than 7/16 to accommodate adding painters tape to the jaws.

Also included Fusion files so and non branded designs.
