Large 4x3 inch interconnecting beach water tiles. I have provided openlock type tiles of left and right corners, side beach with water, and water with no beach. Water with no beach is not shown, but included. I have also provided these designs as top caps that can be placed on your own bases. You can resize them to match "Wyloch" or true tile sizes as well.
The clips for connecting the bases are provided free here. https://www.thingiverse.com/thing:1833963
You could use your imagination and adopt these to other environments as well, such as a bubbling pool of magma or a wizards pool for raising water monsters or a connection to the depths of some deeper or more chaotic world.
I have also provided my 4x3 base that works with openlock and is not available anywhere else that I am aware of.
