Hex dice can be bought here: https://www.mathartfun.com/cgi-bin/sc/productsearch.cgi?storeid=*18cf4080da5fd5f8ee68ac8240f6&search_field=Hex
Or on Amazon.
Also, my original slide deck is below in case that’s helpful - tho the article is great as an aid, because after the practice run you need to be in a room without any electronics 👍
