Helix Puzzle

Can you make the helix move? Just rub the rod on the handle! You'll find out that it's not so easy!
Can you make it turn the other way around? It's harder than you can ever imagine.

You can find a demonstration here.

A little bit of assembly is needed
Print all three parts, the handle, the cilinder rod and the helix.
Then find a screw and assure the helix to the pointed end of the handle.
The screw hasn't to be tight. The helix should move freely in all directions.

Enjoy!
I love this little brain teaser. It took me years to make the helix move, and even when it started turning around, I couldn't make it turn the other way. I got it wrong all the way :D

This is my very first design. So please, if you managed to print and assemble it, I would love to see your photos!
If you can make it turn, share a video!
But above all, please, keep the secret!

Have fun!
