An EXTREMELY poorly written attempt at making a heart shape out of a mobius strip. Using the following equation x=16sin^3(theta), y=13cos(theta)-5cos(2theta)-2cos(3theta)-cos(4*theta) taken from http://mathworld.wolfram.com/HeartCurve.html

There are 3 cross sectional shapes to choose from: rectangle, ellipse and pill

Oh, also there is code in here for a standard round mobius shape I used as a sanity check if you want to comment it back in... just added a variable (heart) to let you use a ring or heart shape set it to 1 or 0 respectively

Rendering this in openscad will take a disgraceful amount of time at present. My old crappy work computer's fan has been screaming for 15 minutes working on this.

Key Variables:

angular_resolution=1;//how many degrees per cross sectional shape, smaller implies higher quality, if you see gaps between the segments of your model decrease this or increase extrude_height

//shapes, set a single of these items to 1 the rest 0 i.e. for ellipse shape... cs_pill_shape=0; cs_ellipse_shape=1; cs_rectangle_shape=0;

// shape_dimension_a=3;//how long your cross sectional shape is shape_dimension_b=1;//how wide your cross sectional shape is

//if you see gaps between the segments of your model increase this or decrease angular resolution extrude_height=0.1;

0. Open .SCAD file and set variables to appropriate values
1. Press F5 and adjust variables if necessary
2. When shape is satisfactory press F6 and got have dinner
3. If it's a long dinner it will be rendered by the time you return and you can export a .STL file
4. Print
5. Give
6. Bask
7. Receive Love &/OR Kudos
