This is primarily what my 3d printer has been doing for the last few months. Printing a small walled city for Warmaster.
This entire project came about when I was looking at some 25mm field walls I'd bought a couple decades ago. Some were resin from a company call Armorcraft (iirc) and some were from Pegasus (I think you can still purchase these). The Pegasus ones were pre-painted. I use these mostly for skirmish games, but also as a quick way to setup dungeon rooms when playing D&D. At the time, I was thinking they might work as an old city wall for Epic games since there wasn't anything about them that defined their scale.
Fast forward to a few months ago. I was looking for themed terrain for my Warmaster Skaven army and found some ruins I could 3d print. Along with those, the modeller had made some non-ruined houses. I started printing, found more stl files that would work, printed more. Then I remembered my 25mm field walls and the idea that they'd work well as city walls. The scope kept increasing, I kept printing. Printed and assembled guard towers for the wall, and walk-ways for the walls (not pictured since they aren't painted yet). I'm about 1/2 way done with painting and about 90% done with printing. At some point I need to call it and move on to other things.
