CAD files for PIM458 ENVIRO+

I am designing a Case to house the Rasp Pi Zero, ENVIRO+ and the PMS3005.

Does anyone have CAD models of the PIM458 ENVIRO+? I have PTC Creo, so a STEP file would work best for cross CAD compatibility.

If there are no CAD models, does anyone have the dimension of the board?

I found what I need on the interwebs for the other components, just can not find anything for the ENVIRO+
