This box is designed to be a "to-go" box for your Gridfinity components. For those times when you need to transport tools, parts, etc from your own lair to your local makerspace, a friend's lair or wherever. My son and I independently came up with the idea that there is a need for a "to-go" box at the same time. His design turned out much better than mine, as he had the idea of making the box using the Gridfinity 1x1 box, blown up to 500%. This is not a quick print, so I have not had the time to test the print myself, but it looks like a good design. If you are printing on an Ender 3, or a similar printer with the 235mmx235mm bed, you will have to turn Bed Adhesion off in your slicer, or this will not fit. If you print it, please leave comments on how it works. We'd love to hear from you, especially with any needs for improvement!
