minecrft heart keychain

the model is designed to be easy to slice and for easy printing, the tiles are designed to be black/white (the one single square is the white one) also the base is the red on,

for easy assembly i propose using super glue 

also for easy assembly, i resized the tiles to be a little smaller so that not so precise printers have no problem with printing it 

(tile side=3.21mm / tile base=3.35mm) so if u plan on resizing the model, do it manually so that there wont be any gaps in the model 

have fun
