spiral panpipes
Procedurally-generated panpipes for 3D printing. They really whistle, but they aren't particularly accurately tuned. OpenSCAD file included. It'll theoretically play a chromatic scale (12 notes to the octave) but it's too squeaky to know for sure! …

Hmmm… maybe a gravity feeder producing your own 3mm filament, or some kind of syringe (like frostruder) to make your own stuff…

Making your own corn based plastic is fairly straightforward, but there are some steps which require high degrees of purity. Specifically, you need to create severely anhydrous lactic acid before polymerizing it — even the tiniest amount of water will gum up the reaction and produce inferior product. And that kind of drying is tough to carry out with DIY equipment.
But who knows. Maybe this difficulty will be overcome, maybe a new plastic (like the one above) will be found. At least somebody is working on these questions, where there was no one before except DOW.
