This is a set of 2 printable reeds for use with a Tenor Saxophone. Design credit is shared with my brother T.J., who actually plays the SaxaphonePlayable right off the bed. I did hit the back of them with a coat of plastruct plastic weld near the tip to make sure they were structurally sound. Reed 1 sounded pretty good. Printed in ABS. No idea if it will work in PLA.
