The heart of this sculpture is interchangeable and can be printed separately. I printed the sculpture with my favorite filament (PLA from Polyterra), the heart with PLA-Silk from Bambulab. In my test prints I had the best printing result with:
Sculpture: 0.16mm layer,
the heart with 0.12mm layer.
The large sculpture has a height of 150 mm, the small sculpture has a height of 100 mm.
