Hi,
It seems that we do not have specific 3D models for the RDB2, we do apologize.
However, we have the GLDBOX (which is an RDB2 with an enclosure), in which inside the design resources from this product page (link: GoldBox for Vehicle Networking Development Platform | NXP Semiconductors), you can find the design files of the enclosure.

Don't know if it can be useful.
Aside from this, we don't see much information on this regard. We do apologize.
Please, let us know.
