Some fun with OpenScad again : a puzzle that i found on the web, rendered using 'boxels' and heavy use of arrays. (mooncactus hinted me about using more of these) be carefull, do not open the coloured image unless you want to spoil yourself (it shows the solution) the "ready to print" mode dispatches parts in such a way that it wont give any clue New following MonZon's feedback, now with 'ease' parameter, to give a litle slack where needed
