Funnel for ice cube tray

I had an ice cube mold for 6 spherical ice cubes at home, but the filling needed to be individually. So I designed this models to be able to fill all 6 at once. It is already tested and works.

The picture shows my intended version. As this one is not so easy to print, I also uploaded a version which should be more easy to print.

Edit 20.8.2024: Added my iteration "Version 3", as it improves filling speed, filling amount and is easier to print.
