I made this for a Friend that wanted to give it as a present to his other half, I designed it with their initials in the middle of the heart, I just removed their initials so anybody can use it. I am planning to learn Openscad so I can use customizer to add the letters, and other settings, but it definitely will take some time.

Instructions:

1. Open the necessary files in your slicer (either both of them, or just the case if you don't want the heart)
2. Choose your settings and position them on the bed
   2b. (optional) if you have dual Extruders, and you want to print the heart also, then you can merge them together.
3. Start printing.

Doesn't Matter

No

0.25 or lower

Infill I choose 50%, but is not going to matter, as it is really thin.

If you printed a heart with a printer that has only one extruder, then you will have to glue it to the body. You will need to sand it first so it fits.
