Modular bit storage for dremel

I wanted a way to incrementally increase the easily accessible dremel bits on my bench. This is a simple design. For my use, I hot glued an old mouse pad to the bottom and cut it to fit. This added a non-slip surface and prevented the bits from passing all the way through the bottom plate. The plate is thick enough to be used as a one off but I chose to use them with the clips in pairs.
