Vangoa EWI-100 TPU Mouthpiece

Here's a mouthpiece cover for the Vangoa EWI-100 Electronic Wind Instrument.  It'll probably work for a number of other branded EWI's as well, it seems that the same basic design has been rebranded and marketed by several companies.  I'd thrifted one of these (for $10 - score!) and it was missing the mouthpiece cover.  So I designed my own cover and printed it in TPU.  The design in the project is set to 102% of my original design, this gives the cover just a little more space to squeeze onto the mouthpiece.  I've used a sharpie marker to put dots on the edge of the mouthpiece.  That will allow me to share the instrument, but give each player their own mouthpiece (and I won't get them mixed up).
