Hello! We plan to connect own device to shoulder, on so-called delivery plate.  
Where can I find drawing with dimensions? When there are nice engineering drawings about base unit and head then shoulder part is only outlined.

Hi @kallet, thanks for letting us know. I’ve updated [the tutorial](https://docs.hello-robot.com/0.3/extending_stretch/extending_stretch_additional_hardware/#shoulder) with schematics of the shoulder + a [CAD of the shoulder shell](https://github.com/hello-robot/stretch_tool_share/tree/master/tool_share/stretch_shoulder).
