sphere-magnet cast in oogoo - double ended

neodymium sphere magnets are a fun toy - with one fatal weakness: the nickel plating (that keeps the NdFeB-core from corroding) can get damaged easily - especially around the magnetic-poles where the spheres come in contact with other magnets/magnetic-objects

with these two half molds, using a two step process, it is possible to cast-in two (8mm diameter, neodymium) sphere magnets in a 1mm thick protective shell made from oogoo
