hey there, Daren! as others have already commented, your creation looks fabulous and sounds fabulous! what an accomplishment! do you have plans for making/selling them? particularly fascinated by the mouthpiece shape (searching for mouthpiece options is what led me to melodica world). have been drawn to 3D printing possibilities for making instruments for a year or so (first off, an eidophone, for recreating voice figures a la Margaret Watts Hughes in 1885!). haven’t tried it yet. that’s a project awaiting my imminent retirement from teaching. you’re an inspiration. looking forward to reading the blog entries documenting your process. kudos!
