This is something I did years ago on my tablet using Sculpt+ which seems to no longer be around.
There's no real story behind it though one of my co-workers told me about the giant chicken heart from Cosby's Fat Albert cartoon. Who knows, maybe I was traumatized by it as a child and this is how it's instantiating itself in mid-life :-)
I was able to print this on my CR-10 as-is with no supports though I am using a good printing surface.
I printed at a layer height of 0.12mm, but I have been printing everything at that using CURA. I think I filled this at 10%.
As-is, the model won't stand. I heated the legs with a heat gun and adjusted the lean & feet a bit until it was stable.
I broke the leg on the red heart and super glued it back on before I fixed it's posture...
Valentines? Hide them behind monitors? The kids seem to like them.
