Cardboard Box Handle

I was in search for free storage boxes with a handle. You often see them on heavier cardboard boxes but i cant find a place to buy them seperately. You can use it on any cardboard box but it works best with cardboard boxes with two overlapping top parts.

You have to print both parts.

I used pla and it worked great. 

You can make it even stronger by increasing the height in your slicer.
