Set layer height to 0,2mm
Remember to enable fillament change on layer 11 (before print 11 layer)
For better appearance use red fillament to print heart :)
In my case (on picture), there is little offset, due to my printer :) - model is ok
I added .f3d file of heart base - you can put there your own qr code :)
The author marked this model as their own original creation.
