razor blade scraper with cover

I liked [Mrcleanr6's razor blade scraper](http://www.thingiverse.com/thing:245702) for getting under prints on the bed, but my 22mm x 43mm double edged razor blades were too wide and weren't centered in the holder, so I redrew it to fit. While I was at it, I added a slip cover because I am leery of leaving exposed razor blades lying around.

There is a [new version with blade locking](http://www.thingiverse.com/thing:301592) available.

Or try my [latest model](http://www.thingiverse.com/thing:697672) with superior blade retention.
