Help locating CAD file for motor mount

Our team has been trying to locate the CAD files for a specific motor mount that we have. We purchased the mount last year (I think from AM, but maybe from REV or VEX). We’ve been searching everywhere on the internet, but can’t seem to find the part. I’ve attached a picture of the mount below. Can someone help us locate these files? Thanks
