Hello Guys! A question i have since some month regarding printing objects so that they fit perfect into each other. In my CAD drawings i draw without space between my separate parts, but then i want to print, i have to adjust around 0.4-0,6mm space between, so that they fit into each other, like on my screenshot. In my mind, there should be a way where I can import the whole model and the slicer program recognizes the individual parts and renders them accordingly, so that I can then print out one part after the other. So far I haven't found such a solution. How are you doing? Thank you for your answers! warm regards Andreas
