Music Box (Tune Box) #MakeItLoud

https://www.youtube.com/watch?v=wO3bNYCCWuM&feature=youtu.be I'm 15 and a student in Israel's Ra'anana; I design and print using Inventor and Cura. I've been designing for a year now, and my class does it two years ahead of time. As a beginner at printing, this piece didn't turn out perfect. The Tune Box: A Design I Created & Printed The Tune Box consists of three parts: the handle, the base, and the wheel. The wheel has eight sections, one of which is missing to play music right. The base has three stripes that are 2mm, 3mm, and 4mm thick; each plays a different note. The connection between the handle and wheel uses friction from an extending hexagon on the handle and an inner hexagon in the wheel. Even though metal devices sound cleaner, my plastic one produces some sound. Holes in both the base and wheel show how to put them together clearly. Designing This Piece Was Challenging This idea hit me in class; I drew it on the spot, then got home and started designing immediately. Almost every part failed at first - the handle broke when touched, so I remade it. The wheel didn't fit, but it made up for it with surprising strength; its thin parts even resisted breaking despite my mistake of pushing them down. To make it work, I printed the wheel the "wrong" way due to material constraints. The only part that didn't break was a 2mm thick line; this came out much better than expected and is surprisingly strong. Printing was tricky as well - the wheel didn't have an easy spot for starting print jobs. To get around this issue, I went with an empty space in the design.
