We needed something to help organize cables in our network closets, so rather than $50 or so on some plastic, I decided to make my own organizer.

1. Print out the file with 10% infill and 1 shell and 20mm layer height (feel free to adjust these settings, but these worked well for me and only took about 35-40 min to print).

2. Slide your cables into the organizer.

3. Wrap a velcro strip or cable tie around the exterior to secure the cables.
