Mobius Heart (Q56160)

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(2*theta)-2cos(3*theta)-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;
