I've added some 3D printer files for block retaining walls. The blocks are scale 1' x 2'. With my printer that is about as small as I can go and still get some detail. If I manage better results I'll post them. Also check Shephane's thread as he is developing some really nice stone abutments. He uses a resin printer that can print finer detail than my printer that uses PLA. I'll post some pictures here but there are a lot more on my site with better instructions on how they might be used here... http://1fatgmc.com/RailRoad/3D-Printer/3D-Printer-Index.html The walls come in 10' x 10' or 10' x 20' sections that can be combined in different combinations to work on a wall of about any length or height. You could cut the walls along the bottom or sides to match the terrain if needed.
