This model is a deriviative of World Trade Center by BrentA on the Google Sketchup 3D Warehouse. http://sketchup.google.com/3dwarehouse/details?mid=808bef05686def6fa3b08fd9ebe3d105 Having a model is definitely not the same as having the real WTC and its' people back again. On the 10th anniversary of September 11th, I wanted to print a copy of the World Trade Center. Finding nothing on Thingiverse, I used this excellent model from the Sketchup Warehouse. The original is an extremely complex model. I converted the groups into shapes, added a base, and scaled it way down to a printable size in Sketchup. In Replicator G, I scaled it some more, and generated the GCode for a Cupcake Makerbot with a heated build platform. The towers have double walls, so are not filled with honeycombs.Print See what the geography of the WTC site used to be.This might be improved by adding LEDs to the inside of the towers and a battery to the base. The design has an empty cavity below the towers, which makes it kind of fragile. This part of the stl file should be changed for durability.
