Hi, I am trying to solve a puzzle on the cubic grid with burr tools. I find one possible assembly all right, but no disassembly. The inventor of the puzzle has given me the disassembled parts but I just can't figure out how to put the puzzle together, even looking at the assembly. I'd somehow like to solve this puzzle with computer help. As the inventor tells me, assembling this puzzle requires rotating parts, not only moving them parallel to the axes. This explains why burr tools can't solve it. If I could only get the assembly into a 3d physics simulation, game engine or so, I could try to manually disassemble the puzzle. Or maybe try to write a program that shakes loose parts ... Any ideas? Is there a way to export the complete assembly (to STL?) instead of only single parts? That would bring me one step closer to realizing my idea.
