3D terrain map of San Diego County from Cardiff to Tijuana, Mx. 3MF file expects green in color 1 and blue in color 4 (using Bambu Lab AMS). Ocean and inland water bodies filled in blue.
I printed this at 0.08mm layers in all green prior to colorizing with 0.4mm nozzle. I think the print came out amazing. Extracted from http://jthatch.com/Terrain2STL/ and vertical height exaggerated for effect (otherwise Coronado Island would disappear into the sea!).
The author marked this model as their own original creation.
