Tire lever improved

The slot that catches on the spoke on the original, is 90 degrees wrong.
i can't see how it would work that way, I'm a bit confused about that.
I didn't try to print the original, I just saw that it was wrong.

Well, I corrected that, and it works good.
I also made a small protrusion on the side of the slot too.
That helps prevent it slipping off the spoke.
