Makes a single 1.5 inch spherical chunk of ice.

Easy to print, make walls/top/bottom at least 1.2mm to 2mm thick.

Fill one of two ways; either fill the bottom half over a sink then put the top on then pour excess water out, or put the top on then fill through the hole. Do not fill to the entire sphere area with water, allow some empty space for water to expand as it turns into ice, otherwise you could end up cracking the mold.

Print in a food safe material.
