Nail and Screw box wall mount holder

thingiverse

I needed to have a place to storage my nails and screws without taking up a bunch of my drawer space. I have seem similar products but they did not interlock and where a pain to remove the nail/screw boxes. I created are 3 boxes that interlock and have a cut out from easy nail/screw box removal. Please let me know what you think or have any ideas for improvement. The top box (this is the one that you need to screw to the wall to hold the middle boxes) The middle box (this is the used between the top and bottom box and do not require you to screw to the wall - but can if you want to) The bottom box (this is the bottom box and also gives you the option to screw to the wall but is not required)
