Geo Hart 72 pencil holder

Two pencil holders for helping to assembling George Hart's amazing 72 Pencil sculpture ( http://www.georgehart.com/sculpture/pencils.html ). When finished, they can also be used as a stand.

There is a useful assembly example here http://sumidiot.blogspot.co.uk/2008/11/72-pencils.html
