Flowery Heart

Heart and flowers modeled in Mathematica separately, then using MeshMixer to edit, scale and put them together.
This is also a part for my 3D printing project "Surprise Box".

Thin, etc.
The printable and revised version is named "ReallyFinally3stl_repariedsimplied". This one has been cleaned, made solid, checked errors, strengthened and simplified. Therefore, this one is more suitable for printing. I will test it within a few days and put on the picture of the printed version here later.
Also, since the original flowers were not suitable for printing, I changed the numbers of the formulas on Mathematica a little bit, and get some different shapes of flowers. (If you notice, all the three flowers are different.) It is also interesting to discover that when I change the power of one of the formula, I will be able to generate something that looked like a butterfly! Therefore, I added the butterfly on the new version!
Use for Cleaning and Simplifying: MeshLab, NetFabb Basic.
* Above software are all free.
Update B
Finally finished printing!
I used the powdery SLS material to print it, and the machine used with this material also gave me the hollow effect inside the heart.
:)
I know that SLA should work too! SLA may be more expensive and compared with SLS, it is more fragile. However, SLA could give you a more smooth surface.
