Hey everyone! I'm new to 3D printing and don't have any modeling experience, so I've been looking for free STL files to try with a friend's printer. One thing I‘m unsure about is how to tell whether a model is actually printable. a good preview doesn't always show potential issues with wall thickness, mesh integrity, or small details. Do you usually check anything special before downloading an STL?   submitted by   /u/Street-Vermicelli800   to   r/3Dprinting [link]   [comments]
