ownCloud fridge magnet

An extruded ownCloud logo, scaled to accomodate a neodym disc magnet 10mm x 2mm near the bottom.

There are three stl files with slightly different diameters. Your printer may vary. The magnet should have a nice snap near the bottom when you push it into the center circle.

Different designs include:
* open extrusion of the cloud shape with inner rings visible
* closed flat extrusion with extruded text 'ownCloud'
* spherical roundish cloud shape with extruded text
* spherical rounded cloud shape with embossed text

Embossing (subtracting the text) did not work out in FreeCAD at all. This was done in blender, on imported STL files, where it worked perfectly well.

The *.fcstd file includes a sketch with a full parametric construction of the ownCloud cloud shape originally done for http://www.thingiverse.com/thing:1795275
