While the build manual and parts CAD files help, they don't make a full specification and there are always some blind spots when assembling a new Upkie for the first time. To help cover more ground, there is now a Blender project file showing how all parts fit together:

The project does not detail every screw, but it can help double check and answer questions such as "where does the battery connector fit behind the face plate?" :) An overview STL file is also available if you just want to have a quick look at the assembly. Hoping this helps!
