First of all I can't test it because I never had a 3D printer and if you print it I'll be happy to see it and to see you complete it. what is it ?? I'ts a heart made out of weird pieces and you have to figure out how to put everything together that's it nothing more I think it's everything you need to know about it, Hope you have fun, it shoudn't be complicated :) ps : I never made a puzzle so let me know what I could do better !
