A level 9 Burr puzzle designed by Peter Rösler, dubbed the "devilish seduction".Quoth http://researchweb.watson.ibm.com/BurrPuzzles/Samples.html : This puzzle has 5 false solutions and 1 which can be taken apart. Even in all the false solutions some pieces can be moved. Print and enjoy.The STL files have a .3 mm tolerance, which works just nicely for me. I left the one piece that needs support in a separate file. The scad file requires the burr module this object is derived of. (This is actually the same puzzle that is given as an example thereof.)
