3D printable Heart
Description
A 3D heart! Maybe the most geek present you can make for Saint Valentine's day ;) I generated a set of cubes discretizing this formula: (x² + (9/4)y² + z² - 1)³ - x²z³ - (9/80)y²z³ = 0 | -3 <= x,y,z <= 3 I found this formula some time ago in a website, but I don't remember where :S Update: Now I know, the formula is here: http://mathworld.wolfram.com/HeartSurface.html Take a look at emmett's Exploitable Heart: http://www.thingiverse.com/thing:6190 I had to write a perl script that generates the OpenSCAD code for all the cubes, because I don't know enough OpenSCAD (or maybe it's just impossible, the limitations modifying variables are a strong constraint).
