a prototype of a slide saxophone.
i got the idea while watching a video about old types of saxophones.
I used many parts that i did not make myself.
credits:
mouthpiece: nah_ny
horn:mechadense
horn thingies:porcupine

after printing the parts, you will need to secure the parts to each other.
first, secure the body to the horn (hot glue?) and make sure it fits nicely.
then, take a strap of heavy cloth and secure it tightly to the horn thingies in each end. make sure that it is tight!
the strap should not touch the long hole.
now, attach the mouthpiece (hot glue again)
and put a reed.
hope this works!

(i never actually printed and assembled that, so its pure theory for the time being. please give me sugestions on how to make this better)
