Disclaimer:
Due to the recent incidents (things appearing on ebay) I just want to make something very clear:
I do not allow any commercial use of my STL-files, my designs and my photos!

Description:
Sometimes you just need a simple clamp ... well, at least I did yesterday to seal my tea bags.
Took me three prototypes to get the tension right, but now the clamp is clamping like it should. And it looks like a fish. That doesn't matter, I just wanted to mention it. ;-)
