I wanted to make a Companion Cube themed Dummy 13, so I made a face to match! Created using the same print parameters as the 1.0 Dummy 13.

I printed it on a Prusa MK4S at 150% scale. Included the files for 100% scale for easy sizing up, but the heart insert gets very small at 100%.

Remember: Dummy 13 will never threaten to stab you.
