I seem to remember a major issue re 3d-printing medical things. Early in the pandemic LTT organied an effort to print some PPE face shields for hospitals. It was all rejected. The microscopic holes left in the print material meant it could not be properly sanitized.

A stethoscope touches both patients and providers. This may be a place where smooth non-printed material may be the only sanitary choice.

Are sthethoscopes passive or active devices?
