This is a 3 piece reed case designed to hold oboe reeds. There's the base that you put the reeds in and a two shells that rotate allowing you to have the reeds exposed to the air to dry out, or closed to be protected in your bag. You'll need:
- #10 screw with nut or m5 screw with a nut (20mm minimum length)
- 32 small neodynium magnets such as these from amazon (they are 6mm diameter 2mm thickness but were measured as 5.95x1.75mm when I actually got them).
- 1/16th inch o-ring stock which you can get from mcmaster-carr for $.21 per foot.
The magnets are between the outer and inner shell and give a super satisfying click mechanism when you open and close the air slots. The magnets will stay in if you have the screw in but I'd reccomend gluing them in with super glue so they stay in there, make sure you don't put them in the wrong orientation or you'll end up having reprint one of the shells. I also glued the nut on the end of the screw so that it wouldn't come undone from twisting.
