Power Port Dimensions for UX303LN UX303LA or other 65W Notebooks

Anyone know the dimensions of the UX303LN power port? It's a barrel connector so it should have an exterior diameter and an interior diameter (for the pin). I emailed Asus twice but got nonsensical and conflicting responses.

Ebay listings for what appear to be the same charger say its 4.00 mm by 1.35 mm but the latter dimension seems too big. I inserted a drill bit into the pin hole to get an estimate for the interior diameter and got ~1.10-1.15 mm, but that's a highly unusual size.

My end...
