Melodica Replacement Keys

Ever have a mom who was given a melodica by her father as a child that she cherished so much? Did it get smashed by her ungrateful children to the point of uselessness? Well, that was 37 years ago and I was only 5 at the time... but that's no excuse to not right a three-decade-old wrong. If you're in the same situation and have a 3D printer, don't delay! Print this out and fix your poor ol' mum's melodica today!!

Depending on your quality of printer, you may need to drill out the holes to about 1/16" (or 1.6 mm) to help it slide over the silver hinge wire more easily.

The keys with curved edges need to be printed oriented as-is with support, but they'll turn out great without the need to sand off the square edges of the one I flattened out for support-less printing.

Note: Replacing these keys is tricky, especially with that loaded spring under each one but it's quite doable if you fashion the right tool (see pic). Also, the silver wire that hinges all the keys to the body cannot be replaced with ordinary rust-prone metal wire. Polish it as necessary and reuse.

If you found this useful, it would bring me great joy to see your work - so be sure to share. :)
