I found this page while browsing for some puzzles to machine on my router The Cornucopia Puzzle
I just finished the Gcode for it but still not machined it, maybe someone of you beat me to it
You will need a 210x160x10mm panel to machine all the pieces. The gcode is in mm and the tool I used to generate it was a 1/4" endmill, plunge rate is 2.5mm and speed 500mm/min but you may want to modify this to fit your machine capabilities.
I hope you all like it.
