I made this wall-mounted organizer for small electronics, like resistors.
It consist of two pieces; the base/holder and a divider.
I made this project with 123D Design, a free download is available at http://www.123dapp.com/design.
It took me two hours or so to make and I guess it will take some hours to print depending on your settings. (I haven't tested it)
