Recently I browsed Thingiverse and Printables for models to improve the cable management on my Ender 3 S1. Here’s what I decided to print:

This cable chain makes the ribbon cable fold toward the rear instead of the left, saving lots of desk space. I printed 16 chain links to reach z=270. See the original model for more photos.

This extruder cable holder (V03.1 is better) fits over the existing cable holder and keeps the ribbon vertical to reduce strain. In Klipper, I reduced my stepper_x position_max from 249 to 241 to prevent bumping the frame on the right.

I noticed some alternatives that route the cable in front of the frame, but they seem incompatible with a rear-folding chain. Some designs route a chain all the way to the head assembly, but I don’t want unnecessary mass there.

Next I plan to print strain relief for the bed heater cable.
