Silicone Ice Balls Tray Mold

thingiverse

This is a printable mold for an ice ball tray that creates 45mm (1.8") ice balls, totaling 4 ice balls per tray. I also designed a simple funnel to complement this tray: https://www.thingiverse.com/thing:3205300 All parts of the mold can be printed as is without any need for supports, and molds have room for silicone spill over, which will require you to simply snip it off. You'll need to use a few rubber bands to hold the two mold parts together while the silicone cures. I highly recommend using food-grade silicone, such as this product: https://www.amazon.com/Mold-Star-Silicone-Making-Rubber/dp/B00LU4YFK6 You can get plenty of quantities for lower prices. A quick note about Silicone Mold mix: there are a few hardness levels available, measured by "Shore A Hardness". A simple Google search will show you multiple images to help you decide. For this specific application, an A20 hardness level would be perfect!
