Saw this and thought it would be easy enough to model... sure enough, only took minutes :) I don't own one of these, just modeled this based off of pictures.
The oval part (Restrictor) can be stuck to your door with strong double-stick tape OR for a more permanent option, can be screwed onto the door using the small screw hole and a small screw.
Enjoy!

UPDATE: --------------------------------------------------------------------------------------------
Tested and works great! There is absolutely no way anyone's getting through this deadbolt with a key or one of those devices they use to unlock deadbolts.
