Black Cat Models from France continues to produce new 3D printed accessories.   One of their latest is set 350023b, "Cable Reel with tubular flanges".   This set from Black Cat Models will allow you to upgrade the cable reels found on your model ships, without having to use photo-etch.
The packaging is a plastic clamshell container, with the 3D printed runner containing the cable reels secured to the bottom of the packaging with thick double sided tape.   This prevents the runner from moving during shipping.  As with previous BlackCat product reviews, to avoid breakage while taking photographs, I left them affixed to the tape.

There are 12 cable reels in the package.   The detail on the parts is excellent   Each 3D printed cable reels is a part unto itself.  It has the complete reel with 3D printed cable.  The cable itself looks fantastic.  All you'll need to do is paint and install, after removing it from the runner. 

Close ups of some of the parts details.
There are no instructions in the box, but the packing directs you to the Black Cat Models website.   There, on a data page for the particular item, you will find instructions on how to remove the printed supports that are part of the 3D printing process.
These 3D printed cable reels are excellent.  They are some of the finest 3D printed parts I've ever seen.  The cables look very realistic, and will certainly help enhance the detail on any model. 

This is Black Cat Models set AC350023b, Cable Reel with tubular flanges. They retail for about $6.00 USD, and are available directly from Black Cat Models.   Highly recommended.
