Trombone water Key Extender

This is an extend handle for trombone water key. Suitable for young student who have short hand couldn't reach their water key. The model fits yamaha YSL-354 and also fit various student model trombone. There are 2 different version and one is longer than the other. PLA or PETG tested and printed perfectly. I suggest to try the shorter version if it works as there are less material to affect the sound.
