@runeranch I'd go for an ocarina myself. If I find a 3D-printer that works well in an apartment setting (not pissing the neighbours off with its noise), I might invest in one this year.
@Streakmachine I can only speak for my CR-10S. I really don't think it is that loud. I can't hear it behind a closed door. And I do have a thing for sound (don't like old clocks, tick tack).
@runeranch Well that sounds promising! Not that I really, really care if they hear the darn thing, but rather if I manage to wake the kids if I do some late-night printing.
