LEGO Ice Cubes

A small project to gain some experience in mold-making. Instead of using an existing LEGO brick, I opted to 3D print one more condusive to molding ice cubes (with drafts, fillets, and as little material removed from the inside as possible). A food-grade silicon was used for the mold since it could easily peel off of the cast LEGO brick. The ice cubes are stackable but as small features, the studs completely melt after a few short minutes.
