Dungeon tile

A simple dungeon tile I designed in tinker cad as a birthday present for a friend who wanted to start DMing in the near future. I made them 3 cm because I prefer to have a little wiggle room in between the standard 1 inch base minis. I made a few adjustments since the first model for my friend so i haven't printed these yet so let me know how they turn out. Also, almost none of these have been printed by me yet so if you notice any flaws just let me know so i can fix them. :)

Revised: deepened the cracks to be more visible and fixed an issue with the top 4 stones not sitting properly on the underlying tile.

Dungeon Tile holder is meant to hold 25 tiles for a 5x5 grid arrangement.
100 Dungeon tile holder is meant to hold 100 tiles for a 10x10 arrangement
