Hex Tool Holder Under Shelf

I needed a way to keep track of these hex drivers I used for my RC cars and now with the 3D printer. This takes up very little room and is handy enough to use a tool and place it right back where it goes. I put a small magnet at the end of the storage tube so they won't slide back out from any sort of vibration that could happen with the shelf. I tilted it 45 degrees and they stayed in place, the magnets are 6x3, they probably would have stayed in place without glue, but I put a drop into each slot before pushing the magnet down in. I used sticky back on it to hold it in place while I screwed it in… but really, if you use a good amount/brand of double back tape, I bet it would stay in place even without the screws, these drivers are not heavy. I got the drivers on Amzn but I have 2 different brands and both fit in this holder. I also made the name plate a separate piece so the text can be edited in Bambu easily if you have different sizes or driver types. I have a small screwdriver
