hey there, in the material section there's a mention of "living hinges". if i'm not mistaken it's hidden joints, much like in patrick jouin's one shot stool. i wonder if there's a tutorial or a refernece somewhere on this; i couldn't find anything. if i insert a hinged part in another (separate) object - how close can both parts be together and still be functional? the same question goes for gears, springs... http://www.iaacblog.com/digitalfabrication/wp-content/upload s/2007/12/one-shot-stool.jpg thanks for the help!
