3D printer Flex Chain

I have searched for a real Flex Chain; one that will bend in one direction but will remain straight when forces are applied in the opposite direction.

I am new to fusion 360 so if anyone has any suggestion of how I could have made these things better, please let me know in the comments.
I have a Ender 3 Pro so expect, more Ender 3 related mounts for this Flex Chain.

I have included the step, and the f3d files as well as the stl files as I am not here to make money, I just want people to have something that they like, then use it, and if they need it to work somewhere else or if they want to try to play with the files.
They can give it a try and hopefully that would inspire others to make more things.

I printed them the way that they look in the pictures provided.

I use pliers to squeeze the 'tops' on, so that might be interesting but
it seemed to work for me.

I printed all normal settings hot end 200, bed 60, no raft, supports, or attached brims so nothing to clean
