Here you can find best DIY music boxes with 15, 20 and 30 note scales provided by many different sellers. You are welcome to use online melody editor
to create a punch card for any of them. Please note, that we don't sell any music boxes ourself. Our store section only displays links to offers from Amazon. In case if you have any issues with a music box, that you've bought, we are always happy to give you an advice, but at the end you will most likely have to reach out to its seller.
