So I work somewhere that recently made a 3D printer available to the public. They submit jobs online and then we attempt to print them. People love watching it in action, and one of the most common questions is "what's it printing?" Today I started looking into ways to show people what the finished product might look like. I printed out a screenshot of what we were printing, but what I'd really like is to have a screen that shows off the model in 3D.
Turns out we have an iPad that we're not using, and we have a lock that can be used to keep it chained next to the 3D printer. Now all I need is a good model viewer app. Anyone have any suggestions?We've only received .stl files from the public so far. It'd be preferable if it were free and just had a simple view of the model; maybe it might have the camera rotate around the model?
