I’m pretty fond of these little Velcro straps I got from Amazon that are like 10cm x 30cm, you use them to push all your computer cables into them so you can neaten them up. I’ve got several of them strapped back to back and it’s a pretty decent solution (and being Velcro you can just pull it apart later on)
Cheers for the continual update mate, always good to see how the project evolves
