Squeeze them all! :)
My wife has just asked me to print some citrus juice squeezer, so I've designed it this way.
It seems it works great, as it will squeeze 100% all the juice from your oranges, lemons or grapefruits, leaving just the dry peel.
It is made of two parts which have to be joined together by the screws (the hole diameter is 3mm).
I intend to make also a third part later, which will come in between these two and will catch the seeds.
I recommend using PETG, no rafts nor supports needed.
Just assemble the two parts together using some 3.0-3.5mm screws.
