Directional Freezing Clear Ice Sphere Mold

Directional Freezing Clear Ice Sphere Mold

thingiverse

This model fits snugly inside a standard Thermos, utilizing directional freezing to craft crystal-clear ice spheres. You may need to adjust water quantities and freezing durations to achieve perfectly rounded spheres. All three parts were printed using PLA. Printing the top section in flexible TPU would simplify removal significantly. For added food safety, apply a food-safe epoxy or polyurethane coating and allow it to cure thoroughly.
