I limit public access to my email, so I don't put it in any posts on this public website.
Is the archive file larger than the 120 MB size limit for attachments? If so, you can post a link to a Google Drive or Dropbox archive where I can download your model.
Or do you need to limit public access to your model? If so, you can send me the link to a Google Drive archive by clicking the Reply link under one of my posts. Paste the Google Drive link in that reply. It will be sent to my email inbox, and posted here. Then you can immediately delete the post, but I will still get the email.
