As pointed out by Jan34 it might be useful to be able to print the heart and minion separately (e.g. the heart in red, minion in yellow).

This was not possible in the current design. So I sliced them up :)
Unfortunately I don't have time to test it right now, but if someone feels brave enough, please give it a try and let me know how it turns out.

I have made a first print to test the design and it did work. The arms were a little problematic though, but nothing a little super glue couldn't fix :)
<<<----UPDATE 2--->>>
I added a second pair of minion+heart ("NOBS_...") where I added some connectors so you can plug the heart onto the body. This should eliminate the need to glue the heart to the body and makes it easier to put the heart into the right place :)
