Hyercube Evolution Imroved Z Upper Rod Brackets.

I was having trouble getting an allen key into the bracket to tighten the upper screw on the upper Z rod brackets, so I loaded Scott3D's brackets into OpenSCAD and modified them to allow better access to the screw.

If you're using the OpenSCAD files, you'll need to change the path to the imported files.

STL and OpenSCAD files provided.
