Wall mounted Guitar chord holder

If you have extra wall space but you don't want to buy a mountable chord holder. You can Just print this simple file and mount it to the wall.

It is an incredibly sturdy design and you don't need much infill. 

If you want to print it in a different size it works just as well if you scale it up or down.

I didn't try, but it should be able to hold extension chords as well.
