Screwable lid system for yogurt cups (customizable) V2

At workdays I usually buy a 500g cup yogurt that lasts two days, and I hate to put the cup back in the fridge with just the foil partially torn off.

Oh, and it also works as a transport safety feature for a newly bought yogurt, in case you have any sharp objects in your backpack

* the prototype works; * the screw connection works. Now I can add an owner’s logo to the lid...

As mostly the OpenSCAD-sourcecode is included so you can improve the thing.
