3d San Francisco Bay model

This is a model of San Francisco Bay showing the terrain above water and the contours underwater. It is based on the best available (at least to civilians) DEM and topobathy (dig that word) data.

This version is dimensionally correct with no height exaggeration. As a consequence it isn't a very interesting print. Most of the detail gets lost in the layers. If you want to print it try http://www.thingiverse.com/thing:237159

This is a dual extruder model
