Hello everyone i am still very new to C.A.D. and onshape I have been trying to make a cable chain attachment for the extruder on my Ender 3 S1 Pro, I have made the front and the back but I cant make the twist in the middle, I am not sure which tool to use or how to go about it. the first picture is what i built, the second is what it is suppose to look like. Any help would be greatly appreciated. Thank you

Sweep with a helix will keep the section constant, but won't have the ease-in/ease-out that you show in your second image.
If you want a constant section, you can do this: https://www.youtube.com/watch?v=gJdRixQ-Gpg&t=42s
I would make a very simple version of the cross section, and think carefully of where you want the centroid of the thing that you're guiding to be.
Here's my quick version: https://cad.onshape.com/documents/b704dca6602cd35235bfb66e/w/270af4d0dab12fe121bb7b13/e/4188b5881869e913c1abade71 -

Your document link doesn't work for me - I get an error that it's in the trash.
Take a look at the model I've shared and see if you can implement something like that.0
