About this 3D model

Machineable 2 set mould in aluminium to make a perfect 55mm ice sphere for drinks. Have 3 parts that can be 3d printed for the internal ejector mechanism. I decided on a 55mm sphere for now, but it would be easy to later do a deathstar ice mould or a '8-bit' minecraft like sphere or Scrat's nut from Ice Age. See how it works on this other homemade ice mould(not mine) http://www.youtube.com/watch?v=1Ey3t5dewDg Simulation of machining my part in cam software : http://www.youtube.com/watch?v=SN2oOIItN0k http://www.youtube.com/watch?v=TDgAqggMMok *update* I made new ejector parts, push-disc.stl was made with 5.1mm hole to easyer fit the bar, also made the disc thinner, push-elipse.stl also with 5.1mm hole and slightly thicker elipse as the previous was not easy to turn with the disc ontop. Made a new handle, vectorized the Ice Age logo and made a new handle, should look fun and cool. Pom-slider had a 6mm hole instead of 5mm, replaced with 5.1mm hole and added a 1.5mm chamfer on the inner hole.
