Hand Helix

I need a 3D model made. So I would like an STL file as it will be 3D printed after. Also an FPX format for me to stylize on blender fpr the digital example.

The Design

In the shape of DNA Helix, I need multiple hands holding each other. Please include the forearm on some to grip each other. Clasp the firmly gripping hands or wrists and, like a spiral twist them into the shape of a helix.

What makes the Helix a strand of DNA is the bonds that hold them together. Please make them as well as another hand or multiple hands gripping the helix. The helix should also have varyimng sized grooves (as they rotate, one gap is big and the next small. You can find that on google. If u need more infp please ask.

Please note I would like hands to face random directions, some holding upwards, some downwards, sometimes 2 down and 3 up. Mix it up. The forearm end of the hand (the side that is not gripping the hand needs to be slightly angled so the join isn't clean and smooth. Disjointed and organic. I hope this makes sense.

I know its quite a specific request, so I would really appreciate designers with a strong creative approach to respond. Thank you
