After much searching for a STL converter or even STEP/IGES versions of the current Prusa build I just decided to do the conversion myself and share.

In order to get the conversion to work I first opened the STL files in 3DS Max, then converted that into a .SAT file. Then opened that file in Autodesk Inventor Fusion and converted that into a STEP file. With all of this converting going on I know for a fact that the STEP files are not 100% accurate to the STL files, but they are very close representations that can be used for making a solid model Prusa assembly, or even to copy and modify to experiment with different designs.

This was my first attempt at this conversion so please let me know if you find any bugs or issues with the files.
