Thanks for the info.
I was able to integrate with a fancybox iframe, but it looks like "version" changes numbers depending on how many updates you've done to your model, starting from version=0. one of my model was at version=3, and another was at version=1. iframe width and height is 482x357.
example here:

<a class="3diframe" href="
https://www.shapeways.com/sw/static_html/3dnp.html?total=0180 &levels=5&startlevel=3&model=387585&version= 3" title="3D view of Nomad Panohead +5"><img src="../../images/3d-button.jpg" alt="3D view of Nomad Panohead +5"/></a>
$(document).ready(function() {
$(".3diframe").fancybox({
'padding' : 0,
'width' : 482,
'height' : 357,
'autoDimensions' : true,
'autoScale' : true,
'scrolling' : 'auto',
'enableKeyboardNav' : false,
'mouseWheelNavigation' : false,
'margin' : 10,
'speedIn' : 150,
'speedOut' : 150,
'changeSpeed' : 150,
'type' : 'iframe',
'overlayColor' :'#000',
'overlayOpacity' : .8,
'cyclic' : true,
'titleShow' : false,
'showCloseButton' : false,
'titleFromAlt' : true,
});
});
