I have been summoned!
Yes, @theSLAYER is correct; the zip file was saved on my Google Drive, which since 2016 I have understandably reorganized and cleaned up, and the zip was not a file that survived. However, Ohana3DS Transfigured is still on my Github page, and from time to time I continue to update it. XObj, on the other hand, has been obsoleted by added features to Ohana and is no longer needed. Frankly, I might head over there once I'm done with this post and close that repository.
