1/4 inch (6.35mm) Adaptor Holder

thingiverse

This is a simple 3.5mm to 6.35mm (or 1/8 inch to 1/4 inch in Freedom Units) adaptor holder. I have a lot of headphones and almost every one comes with one of these so I have a large stash of these adaptors. They are handy when you need one which is why I keep them on hand but I never had a good way to store them. They were loose in my drawer and I just got tired of them always rolling around and getting in the way. So this was my solution. I probably over engineered this a bit for a just a jack caddy but I wanted something that was clean looking and very stable. The adaptors are also easy to grab when you need one with this design. The caddy should hold 10 adaptors. All of the various adaptor designs that I have on hand have the same diameter (or smaller) in both screw on or snap on. So, regardless of type, they should fit, although you might have extra space if they are slimmer. The opening is just one long slot for maximum compatibility and to save on printing time but this does mean they can slide back and forth if it's not full.
