Wayfarer Tactics 28mm - Complex and Chemical Pool Tiles based off of the "Wayfarer Modular Scifi Gaming Tiles: Core Set" ( http://www.thingiverse.com/thing:703514 ). Set to the scale of the "Wayfarer Tactics: Modular Terrain System (Simple Stonework)" set ( http://www.thingiverse.com/thing:963555 ). Mostly so I can use them on the TileTray that's included in the Simple Stonework set. :) Oddly, thingiverse won't let me add more sources... so here is a list of other things I used when I started adding tiles: http://www.thingiverse.com/thing:797968, http://www.thingiverse.com/thing:201824, http://www.thingiverse.com/thing:843594, http://www.thingiverse.com/thing:15937, http://www.thingiverse.com/thing:26566, http://www.thingiverse.com/thing:645121, http://www.thingiverse.com/thing:797810, http://www.thingiverse.com/thing:884154, http://www.thingiverse.com/thing:859833, http://www.thingiverse.com/thing:33140, http://www.thingiverse.com/thing:610951
