      <title>Halbach 12 Magnet Laser cut</title>
      <link>http://www.ponoko.com/showroom/EdgarCastelo/8615</link>
      <description>1 - Put the Arrow piece, the one with the Magnet Axis Directions, on the bottom.
2 - Put the first Square piece, the other pieces, with the square holes, aligned and on top of that. Glue the two, on the outside.
3 - Using 4 Magnets as place holders, stack the other 3 Pieces, and glue the lot on the outside.
4 - After finding the North of each Magnet (a Compass South poit points to it) mark it with a Permantent Ink Felt Marker.
5 - Put the Magnets carefully, the arrows point to the North, put them, first 4 spaced 3 places apart, glue the top, then 4 to the right of those, glue again, then the remaining 4 glue again.
That's it! :)&lt;br&gt;&lt;/br&gt;&lt;img alt=&quot;Imag1465_showroom_image&quot; src=&quot;http://static0.ponoko.com/design_images/images/1600/f70c8f6e-666c-5af7-fa9d-1638f2a9d0d9/imag1465_showroom_image.jpg?1347125848&quot; /&gt;</description>

      <title>4 Halbach Linear frames</title>
      <link>http://www.ponoko.com/showroom/EdgarCastelo/8618</link>
      <description>The pieces for four Linear Halbach Magnet Arrays, for 10mm Magnet Cubes.
The  base shows the proper orientation, for each Magnet.
Looking at the arrows, with both outer arrows pointing left, the bottom side is the strongest side.
