This is the first diorama I set up with the dungeon tiles I have printed over the last two weeks.
I put a copy of the original plan next to it for comparison. All the tiles were part of the True Tiles sets, except for the unholy symbol at the far end, which I designed myself based on the symbol of the water cult. The cultists, priest and shark are for decoration and aren't a spoiler of the content of the room. The 59 tiles took about a full week to print, and used about 1 spool of Z-ABS (800g) for €35, including the wasted material for rafts and supports. A cheaper material would probably also have worked, but I like the color of this one.

I've printed extra parts beyond this, and am now on my third spool of filament. That should give me enough of an assortment of tiles to reconstruct the whole Temple of the Crushing Wave from the Princes of the Apocalypse adventure. Not at the same time, mind you, but room after room in function of the movement of the group. And I can re-use the same tiles (except the water) for the other dungeons.

I was thinking of creating cave tiles to build the first dungeon of the Lost Mine of Phandelver in the 5th edition Starter Set, Cragmaw Hideout. Somebody did that with another tile system; but he needed to make the tunnels much wider (4 tiles instead of 1 tile) than on the original map to get there, and then needed polystyrene foam blocks as a support for the elevated rooms. I think I'll stick to dungeons with just one level, and simpler caverns. The tiles are easy enough to create quick battlegrounds in rectangular rooms, but for complicated irregular rooms with different levels a printed map might be better.
