Prepare High-Detailed 3D Scans for Printing

I have several 3D LIDAR scans of dinosaur footprints that need to be prepared for high detail 3D printing. I need you fit the scan model on a standard size square plate (150x150x2mm and 50x50x2mm), exaggerate the vertical axis by 2x, make sure no part of the model is less than 2mm thick, make sure the scan is oriented to make the best use of the square plate and to minimize printing materials, and and provide a STL format file. Some footprints are impressions (depressions in a flat surface), some are casts.
