Futuristic city builder generator

thingiverse

Hi! This is my first customizer, a simplified OpenSCAD version of a program made with Processing (http://www.processing.org) a few years ago. With this customizer you can generate a sort of futuristic buildings/cities/ships. You can choose the shape and size of the base then the algorithm fills with a 3D-recursive structure. As a random generator, it depends on a numeric 'seed'. Every seed generates a unique structure. This seed is printed at the bottom of the base as a reminder of your unique design and may be useful for reproducing the structure. This thing combines great with Customizable Convex Polyhedra http://www.thingiverse.com/thing:233540, printing incredible stands for your future-cities. See the instructions and photos for more information about parameters of customizer and how to merge with polyhedric stands. Also included: The STL file with Truncated Dodecahedron generated from http://www.thingiverse.com/thing:233540 and tested with polygonal bases (10/3 sides with side length of 9.75 and separation of 2mm). And some STL's And a ZIP file with many figures generated during development (before the final and customizable version) Have fun! UPDATED (2016, July 30th)!! Modified a bit of geometry on some parts to avoid overhanging problems when printing big figures. Results are similar but there is a little change in the overhangs of 'pyramids'.

Infill recommended 15%-25%. You can print with no infill but the roofs and flat parts may print badly. Infill acts as a support from inside. Rafts/Brim: Only if you really have adhesion problems. Supports: NO!!!!. Geometry has been designed for no supports. The program adds its own supports if needed in one special case: A polygonal base smaller than the figure. Instructions for Customizer Some explanation about parameters. General Parameters Seed: Number for the random generator. You can use up to 19 digits. Base: Initial base for the structure. Can be a Polygon, Rectangle or Circle. Each one has its own parameters. Base Height: Height in millimeters for the base generated. Poligonal bases Needs number of sides and length. Position: Specifies if figure fits in (inscribed) or out (circumscribed) to polygon. Separation: Margin from inside (when inscribed) or outside (when circumscribed) to polygon. Rectangle bases Sizes X-Y width/height of rectangle Circular bases Diameter of circle. Example of poligonal base with supports. A big rectangle base can generate a nice city. Sometimes circular bases generates big towers. Using a polyhedric stand Generate and print polyhedra Question: HOW? Answer: Customizable Convex Polyhedra http://www.thingiverse.com/thing:233540 Measure the length of the sides With a ruler or caliper. Create a poligonal-based figure with number and length Begin with a small one and check it fits. You may need to adjust the length of sides to obtain a good fit. Choose 'circumscribed and a separation of 2 or 3 mms. Good luck and have fun!
