Not Hole Punch Hole Punches

Today was a free day so no lectures, so I was able to get lots of work done.
In Mechanics I was given this brief:

•  Design a device for making two 6mm holes 80mm apart and 10mm from the edge of a sheet of paper

So yeah, a hole punch..... that isn't a hole punch.So anyway here are the designs I have come up with, to be honest I think the last one is my favorite one, you'll see why.

So there we are, hole punches that aren't hole punches..... sigh.... what next?
