My first post, quick question From a design point of view, how structurally sound is a wall 1 mm thick for let's say Strong and Flexible material? For example, let's say you modeled a tray for Strong and Flexible material with the following bounding box dimensions: 9cm x 5cm x 2cm. Would a wall of 1mm thickness be too brittle? Warping shouldn't be an issue since the thickness-length ration should be fine. Thanks in advance for your help.
