Impossible dovetail with rotate and slide mechanism

When I saw the impossible dovetail I was psyched and had an idea to create this puzzle with a twist (literally ;-)), so I here present you guys my rotate and slide dovetail puzzle.
You can only slide it open when it is rotates in the correct orientation.

For interested people, I can create a youtube video of how I created this part in Fusion 360.

Now the first version is not very good, I made a mistake when creating tolerances (my first week of Fusion 360 experience ;-)), but it is also my first 3D printed piece ever and my first puzzle ever, so I am proud of it :-)

Here is the piece in action:

Of course, not a problem, but the current design is a bit of a failure, so I am planning on improving it, so then I can share it.
It has some very sharp edges and that I also want to make better. Maybe if I just create a tutorial how to create it in Fusion 360, it is better, because you and others get to understand how to design such a thing.

Created another version that also needs to be rotated first and then slide it. I love the curvedness more and it is a single dovetail which I like more.
