Why don't you just print them then? The copyright police is not going to barge into your home, and even if so this might fall into fair use (depending on your circumstance/situation/etc).
I’d interpret it as offer to support the project and receive high quality prints. The author is clearly gifting the world an incredible portfolio; one ought, if able, to financially support such unique, open datasets.
Agreed, but from the thread it seems the author is very hard to reach/doesn't have a store/etc.
