My model of a broken heart as a keychain.

It can be printed as is, or you can add a pause at layer 16, to have a different colour heart and base,

I can't upload my 3mfs due to some incompatibility with modified g code, so please upload your makes and profiles :-)

I normally print at .2 layer, with a .4 nozzle and 10 to 15% infill, but you can do however you like.
