Spit Catcher for Yamaha YDS-120 (Black) - 3D Printed I've been making various DIY spit catchers since I bought the YDS-120, and I'm finally happy with the result. It solves the problem of accidentally getting your sheet music wet or noticing moisture on the instrument. Use it by folding a tissue and inserting it inside. This is the improved second-generation spit catcher, with increased contact area for improved stability. Fits the loose, square-tapered shape of the YDS-120. Thank you for looking.
