use good ideas from page http://woodgears.ca/tool_holders/toolchest.html.
I found it very convenient to have a panel that is not complicated tools extraery save them, so use neodymium discs to hold.
each disc holds 1.7 kgs so the tools do not fall off when you close the box
When I'm designing a neodymium disks are hidden.
