This is Easy Mesh Exporter that is inspired by Mary Cassin's FBX Exporter at http://marycassin.com/.
To save the mesh for the game, you need to bring mesh to (0,0,0) position, look for export on the menu, locate the path, and save it and bring it back to the original position. It probably takes around 1 minute to save, but it is repetitive and annoying.
This tool exports FBX and OBJ too, but it also moves the mesh to (0,0,0) position, saves, and brings it back to the original position. It also shows whether it is saved or failed.
Here is the link to the Maya python script.
