I needed something to keep order of my headphones, I do not have a massive collection but I have a few and they all have their uses. On the head-fi forums there was a tip about using IKEA GRUNDTAL toilet roll but that made think about the BMX Pegs the kids where not using anymore.
The pegs are screwed through the back of the desk using M8 bolts. Very simple and the wide diameter of the pegs give a nice round surface for the phones to rest on.
The desk is an other project, a height adjustable office desk I bought second hand.
I removed the board because I needed more space and made a new one from MDF.
