Gazebo String Light Clip

Having bought a 48ft string LED lights(something like this here: https://www.amazon.com/dp/B07DFGY6N8); this was for our metal gazebo in the backyard. I had to figure out how to 'professionally' hang them around the metal roof members inside it.

Now, having assembled the gazebo myself a week before, I surely knew that the members was 1"x1". So, I quickly went about sketching a hook clip based upon a 27mm square profile that I could latch the cables onto.

Fortunately, the rough dimensions that I had considered came out perfectly! I must be getting better at it ;)

Anyways, let me know what you think about it. I am attaching the FreeCAD files for your customization.

OK one printed, 20 more to go!
