Ice Sphere Maker

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)

*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
