Summary

Cable ring is a fully 3d printed cable management solution consisting of rotating slotted rings in bases.
remove, replace and reroute cables any time in seconds without cutting zip-ties or dealing with messy cable bundles.
Simply rotate the ring up, slide the cable in then rotate the ring back down to lock it.
Supports a wide range of wire gauges, from thin audio cables to thick power cords
The base can be screwed, zip-tied or glued to any mounting surface.
Gallery of different curved and straight plates allows for tidy routing and splitting cable lines.
whole assemblies can be resized in slicer software for your preference.
There is a whole array of available types and sizes of bases and rings
low tolerance of the design means that it can be printed on any printer and will still work.
Can be printed with all common filaments, such as PLA, PETG or ABS

(the high tolerance version of the ring is the most snug fit i could get on my ender 3, it's a perfect balance between free rotation and staying in place, if it ends up too tight for you, try the low tolerace version and tweak the XY contour expansion setting in your slicer software or resize the ring ever so slightly (+/- 5%)

The rings must be printed laying flat then push-fit into their slots in the base. If you struggle to get them in, try rotating the ring 90 degrees with the slot facing sideways. I reccomend printing the rings in different filament color for aesthetic effect. There is no need for supports or brims due to large footprint.

My prototype prints were printed with PLA and PETG, PLA for the bases and PETG for rings, petg seems to work for rings as the slight flexibility makes it easy to slide them into slots, PLA rings were difficult to slide in, but end up sturdier

I named and placed all files in a file tree to easily find the needed versions of models for ease of use.

the majority of files were not test-printed or sliced so there may be some errors or misalignments.

[Update 1]
After much testing i found out that long, thick cables, namely power cords under a desk, cannot be kept tidy with just ring bases as the excess hangs down. Routing the cable through the same ring multiple times would solve the solution but the default rings arent wide enough. So i added this bundle ring

A much wider ring allows for routing the cable back and forth multiple times to tidy up excess length of cables. The bundle ring is not push-fit into the base, instead, the ring has to be twisted then slid into its base. angled hole on top of the base allows for screwing the base with a hidden screw inside a base

[Update 1.01]
Fixed some models that had flipped normals and misbehaved in some slicers. Also added the bundle ring to the archive
