About this 3D model
This is a simple 3 board burr puzzle that should be printable on most 3D printers. http://puzzlewillbeplayed.com/3BoardBurr/Carbon/ I used an eMaker Huxley with a 0.3mm nozzle. EDIT: The XMPUZZLE file is now also available for download. Get a copy of Burr Tools to open it (http://burrtools.sourceforge.net/).
