juice squeezer

###The story:
When life gives you Lemons...

...print an electric lemon squeezer. It actually started with a big sack of oranges I bought on a budged a while ago. They were too much for me, so I decided to make some juice. But there was no squeezer. Obviously this is one of the ever-growing number of problems in life that can only be solved with 3d-printing.

###My goals:
* 1: Design a squeezer for ~1/2l of juice
* 2: Make it motorized because why not?
* 3: Use a graceful way to activate
