I have need for a nice harness to hold onto my Gumstix Overo Summit expansion board.This thing isn't so much a derivative, but an application of a set of parameters to the general pcb harness OpenScad tool.It fits the Summit board in such a way that all the connectors are free and clear, for easy connections. The included OpenScad file contains plenty of other ready measured boards in it as well. It's fairly easy to create your own board harnesses. Just measure, change parameters, print.1) Print one 2) Slide your Gumstix Overo Summit expansion board into place 3) Rejoice!
