I'm new to 3D printing, but have the opportunity to work on preparing a architecture 3D model for print. All I know of the project is the scale (1:12) and nylon as the material. I want to ask all the important questions before I start so I can reduce the amount of re-work if there are problems. What other questions should I ask before I start prepping the model? Should I ask what the thickness requirements are for the walls?
