There are lots of cable storage for gridfinity here, but I couldn't find anything that satisfied my music cables, specifically because they were so much larger than your standard usb and the like.

So I remixed these, 6 different variants, in order to organize all of your XLR, ¼ inch, speaker, and misc music cables from sizes of 1ft all the way up to 50ft depending on the cable. I added the center cutout to make it easier to grab the cables out. I also made them lightweight so they could flex just a little in order to make it easier to put the cables back in their slots and even bury the leads in the slot as well.

They're labeled according to what I was able to fit in them, but if you're unsure which to print, assume that ¼ inch cables like balanced and instrument cables can fit into the larger end, and thicker cables like xlr and speaker will fit the smaller numbers. (Ex. the 15-25ft variant can fit a 15 xlr or a 25 instrument cable)

These have the magnet bases underneath, they're especially helpful for the 1ft variants.

I'll update this with any other sizes I end up needing, or any other variations that can help me keep my mess organized. 

Please post a comment with a picture so I can see all those studios cleaned up!
