USB cable reel (stackable)

USB cable reel to easily store up to 2.5m of USB cable.
It was designed to be easily printable with 0.6mm nozzle without supports.
Scaling down to 67% will give you a perfect reel for 0.4mm nozzle and up to 1.5m cable.


I wanted a sturdy / durable cable-reel that was easy to priint.
I also want a system that lets me easily store multiple cables and choose which one to use.
I came up with this thing (inspired by thing:4397993 ) that allows me to stack multiple cable reels and still being able to use and later store each cable separately. (even while still stacked)

It works perfectly as designed and is a huge iprovent to the mess it used to be, But I am still not super happy with it yet. I feel there must be a better way to accomplish my goals but I have not come up with a better solution yet.

So Any ideas to improve on my design, or any other way to acomplish the same goals are super welcome!
