Also Edit: The tiles are fixed, as well as some new ones added. Located here on Drivethrurpg "Pay What You Want".
I printed mine up and glued them to chip board. It's sturdy and they come in 6x6 packs, which is nice. The one down side is that they do add weight as the stack gets thicker.
Although I did notice another mistake. I will have to correct that later as my weekend seems booked.
