magnetic hex bit holder

[mklotz]

Well done and cleverly designed.

I bought a few of the commercial version of what you've built...

and I love them for the seemingly endless variety of 1/4" hex bits that accumulate. Having a magnetic base so they can be stuck to the vertical sides of tools boxes/carts is another real convenience.

The same design is available for socket storage...

They're meant to have standard sockets in the front row and deep sockets in the deeper holes in the back. That would require two separate holders for metric and inferial if you happen to live in one of the backward countries where inferial is still used. I comprised by keeping deep inferial sockets in the front holes and deep metric sockets in the back holes. Personally, I've found very few situations where a deep socket can't be used instead of standard. They probably exist but I haven't stumbled on many.
