Juicy Salif

This model is only for show and isn't supposed to be used to actually squeeze oranges, since it is 3d printed.

Printing:

Import the model into the slicer, scale it to the size you want and rotate it by 180 degrees on the X axis. 

Then paint the support on these places (you can adjust the supports to your needs):

So it should look like this:

This is in my opinion the easiest way to print it without cutting it up.
