First I made a bell, which if all the restrictions for fusing and such with stainless that I have read are true should at least make a noise. Don't know if it'll ring, but I hope it will. Can't be too sure about that with my latest and greatest noise maker. I've drawn up a music box, and it is dimensioned to be stainless printable. But will it play music? I hope so. Won't know till I have $65 extra on hand. Unless someone else would like to test for me Very Happy

Michael,
I looked at your design and I think you would be disappointed with the sonic results if you actually were to print the "keys" or twangers as I call them. In order for them to resonate they need to be very thin and resilient. There is a reason traditional music boxes have used spring steel for this purpose for hundreds of years. Also instruments like a Kalimba (thumb piano) use hardened spring steel for the twangers.

If the keys were printed they would be fragile and subject to stress and/or fatigue cracking. And would also be very difficult to tune. Better idea would be to get some steel "music wire", Then print a support bracket with a row of small holes into which you could insert the music wire. You could also use flat spring steel strips for the twangers. A cheap substitute to experiment with are the strips of steel used for banding shipping crates.
This stuff is free, it is hard enough to be springy and you can cut it with a decent pair of tin snips.

I was going to try this out, see if I could get it to work using the machine shop at my work. If it's not possible with the printed stainless, then I have a music box at home that I can steal the pre-tuned music maker, and redesign the drum to work with it. My hope is for a personalized music player.

Hi Michael,

cool you are doing this project. This is something we have been thinking about also. I agree with Glen that it is best to get a tuned set of 'twangers' and print the drum.

What a cool creator, upload your tune and get a printed drum roll.

best regards,
Peter
