Grabcad has some models you could download....
I've had good luck here GrabCAD in the past with miscellaneous electronics and such.
Digikey usually has links for 3D models when they can make them available. Also distributor or manufacturer web sites.
ALWAYS check model against product spec. NEVER trust a EE's mechanical model/outline/representation.
What about 3D ContentCentral ?
I have couple (single and dual ports) which I downloaded few month ago
