One of my first designs. Any input is very welcome.

See http://openstructures.net/pages/9 for more information.

This is a mold generator to measure and mark holes according to the OS Grid.

Use the holesX and holesY variables to make your own size.
Adjust line width etc for sturdyness vs weight (weight also
meaning cost, printing time etc).

I printed a few of these in different variations on our MakerBot Replicator 2. Recuding the variables for line width has led to a few failed prints. (More documentation is in the scad file's commentary).
