Re: gEDA-user: gEDA mounting hole for screws

["Phil Taylor" <phil@xxxxxxxxxxxxxxxxxxxxxxxx>]

Frank:

Here's a screwy screw hole.  Save it to your footprints library, edit it, etc.
 The arc is in silkscreen, so as to show you how big a keep out area you'll
need for the screw head + whatever wiggle room it needs to keep your circuits
and mounting hardware isolated.

The sizes are set as per Stuart's file:
