Draw Latch

Many of you really liked my reversible hinge. I saw that the projects they were being used on involved boxes that used some kind of draw latch like this one. I decided to make a latch that matched the hinge in size and style. 

I have not yet printed this part so I am very open to comments and suggestions about how it functions, if its strong enough. 

M3 Counter Sink machine screws, will upload blueprint of the dimensions soon.
