rounded off the stems and shortened them a bit to fit my head. also reduced the size by 1% to fit the lenses I bought from ebay(search "POLARIZED Replacement Lenses for-OAKLEY Dispatch 1 Sunglasses-Multiple Options" from highprecisionoptics )

updated:

changed the hinge so you can use a standard sized screw to attach the stems, rather than the print in place hinge.

altered the stems to fit my head / ears better.
