For several years I have been writing computer software to explore the space of traditional 6-piece burrs. I have worked with Bill Cutler to reproduce his original results, and I have extended that work in small ways. One goal I had was to build a small set of pieces that are easy to make, and allow many combinations of 6 pieces that can be solved. This is the first set that I like. I have included a PDF describing it, which includes a sequence of 10 puzzles of increasing difficulty. I believe that if you progress through these 10, you will become better and better at solving the basic 6-piece burrs, and will be ready for greater challenges. This stl was generated with Enso (http://www.jeremyrayner.com/puzzles/enso/) from the an .xmpuzzle file. enso will output OpenSCAD (https://www.openscad.org/) files which reference Aaron Siegel's excellent Puzzlecad library (https://www.thingiverse.com/thing:3198014) to do the final rendering as an STL. For printing, I suggest using a raft. Printing directly on the bed tends to make the bottom layer or two flare out at the perimeter, which can interfere with the quality of fit. Also, note that with more play, the pieces tend to get a bit looser, so tweak your initial settings for a slightly tight fit. I hope you will enjoy these puzzles as much as I have!
