Filament Box Handles

I had a filament rack on my 3D printing desk with enough room to slide a filament box under it. I was storing spare printer part, hardware, and some not so frequently used tools. I was finding that the boxes could be hard to pull out sometimes, so i wanted something to grab onto as well as label what is in each box. This is exactly what i was after so i whipped up a model. I have included a blank for own labeling. There is also a template that can be quickly printed to mark the holes for exact placement on each box. I used a pair of M4x10 bolts for each and just let the bolt thread the hole.
