With these files you can easily make your own adapters.    
For best compatibility be sure to use the win32 version of Eagle 7.6.0 downloaded from [here](http://eagle.autodesk.com/eagle/software-versions/2).    
All PCBs were autorouted with FreeRouting for which you need the [Java 8 RE](https://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html).
