I call this “Heart in a Jar”, Colored with Hueforge. I tried to represent the resilience of the heart. Size is 200x200mm, I included layer heights if you want to experiment with other colors. If you want to change a color, I would recommend the grey/silver, as I played with several other colors and they all looked nice. Also included is a print profile for if you do not own an AMS, I added pauses to the appropriate layer heights for filament change. Let me know if you find any issues.
Print at 100% infill with a layer height of 0.08mm with a base layer of 0.24mm. My Included 3MF has a height modifier to print the base layers more quickly. (See below)
Filaments Used:
PLA+ Sunlu Black Transmission Distance: 0.6
