Sobre o objeto 3D Script de criacao de anel

Este é um arquivo desenvolvido e projetado com ferramenta CAD.

Se você ainda não sabe criar seu próprio modelo 3D eu te ensino neste artigo tutorial sobre Tinkercad.

Script de criacao de anel foi projetado para Impressora 3D. This OpenSCAD script will generate a Tiffany Etoile style ring with a tension/Bezel/Partial-Bezel set jewel mount for a brilliant (round) cut diamond or similar shiny thing.Most parameters are user selectable as are the ring profile shapes.Potentially very useful when combined with the following:Ring metal cost calculator http://www.thingiverse.com/thing:12589Diamond size shape weight conversion Spreadsheet http://www.thingiverse.com/thing:12586Ring Size System Coversion http://www.thingiverse.com/thing:12689for creating and costing a custom engagement ring or other such tomfoolery.Todo:add option to round edges on crownmake gap between 2 sides of crown slightly smaller than required to exert pressure on sides of jewel to hold it in place for proper tension set performanceadd complete roman font polygons for engravingimplement hidden compartmentWarning:Let the right one inChanges from previous versions:0.14Replaced deprecated import_stl with importAdded control variable "generate_jewel", if 0 import the jewel from "brilliant1.stl", else try to generate it on-the-fly (this may cause errors as pointed out by mrchriseyes)0.13Added Simple internal engraving functionality (you will need to create a custom polygonal script though!)Finally got the person's ACTUAL ring size!6 6- USAGrooves for diamond were too small Need to scale stone by about 1.07 to acount for diameter loss0.12Added Secondary Crown to make it more similar to Tiffany Etoile SolitaireUsed Render() and gave option to load the Brilliant cut Diamond shape from external STL file for better previews (the complexity was causing CSG rendering to be disabled)Added additional code to ensure the inner surface of the ring is preserved and smooth as crown shapes could poke through, creating sharp edges on inside of ringFixed colours on certain areas0.11Fixed issue whereby rounded rectangle shape CS appeared slightly translated in Y direction (taken from Ring_band_creation_script_v1.1.scad)Added extra cross sections (cs_half_pill, cs_reverse_hemi_ellipse, cs_reverse_rounded_hemi_ellipse taken from Ring_band_creation_script_v1.1.scad)0.10Round edges on cylinder unched through centre of crwon to back of ringAdd option to have side supports on crown0.9Added user variable to control colour and opacity of jewel and metal materialCan select which type of split you want for the crown (none, rectangular, bowtie, both) by setting with_bowtie_split and with_rectangular_split to 00, 01, 10 or 11 respectivelyCan now choose whether crown is splayed out/tapered or notFinally remembered to difference the brilliant cut gem from the ring to make the groove to hold the brilliant cut round jemstoneAdded ability to specify diamond size in Carats to specify girdle diameter, assuming a round cut close to ideal it should be reasonalby accurate (based on data from http://d.neadiamonds.com/diamond-carat). Relationship appears to be close to power or logarithmic curvePower Curve size[mm]=6.5065412147(Carat^0.3381325352), confidence value R^2=0.998Log Curve size[mm]=1.964367652 Ln(Carat) + 6.6289134546Changed most crown variables so that they are influenced by the size of the stone chosenDe-deprecated some variablesAdded new cross sectional shape cs_rounded_scallopped_rectangle0.8Added outwards splay/taper to jewel setting based on size of crown face and size of ringIdentified some redundant variablesAdded additional cross sectional shapes (chamfered rectangle)Fixed some CS that resulted in internal diamteres less than expected (cs_rounded_hemi_ellipse, cs_rounded_rectangle, cs_chamfered_rectangle)0.7Added ring sizes from 4 systems based on linearisation of data found here http://en.wikipedia.org/wiki/Ring_sizeAdded acitional cross sectional shapes (rounded rectangle and chamfered rectangle)0.6Added multiple user selectable cross sections (rect, ellipse, D, chamfered, filleted, scallopped)0.5Added ability to make a bowtie shaped cutout through the jewel mount and ring, 'cause it looks cool!Added ability to color the ring & crown part of the eh... ring!?0.4Fixed issue with internal diameter of ring not being that specified by userAdded ability to control width of rectangular split/cutout on jewel mountAdded ability to control depth that jewel mount overlaps band of ringChanged cylindrical cutout in jewel mount to be conicalAdded an actual scalable brilliant cut diamond shape (with ability to give it a "color") within the jewel mount(pretty!)0.3Changed to pill shaped cross sectionAdded rectangular cutout on jewel mount to make split/tension set type fitting, it doesn't line up correctly though :(Added commented out/empty calls to functions to enable rest of functionality I desire0.2I don't think I ever got around to changing this version, please ignore this :p0.1First attemptMakes rectangular cross section ring with hollow cylindrical shaped mount for jewelAllows user to define feature size
