Summary

I customized a 10 x 10 Hex Bit Holder to include a solid base so that the bits don't fall through the bottom of the holder when I move it. This makes it easy to take all of my hex bits with me when I'm working on a project rather than needing to return to my toolbox each time I need the use a different bit.

The original design was created from a customizable bit holder:
