What would YOU do with a 3D printer?

Let me add to Linda’s comments about noxious substances and air
quality. I recall a statement made at an environmental issues
conference: “The largest hazardous waste dump on Earth is the
atmosphere.”

Every time comments are made about the need for good ventilation
(which is very necessary), I have to think about where those fumes,
etc. go. the atmosphere. Whatever we can do to reduce our ‘noxious
footprint’ can only be animprovement.

Judy in Kansas, where a frost this am means it will be time to clean
up the plantings and garden. Just saw the first junco at the bird
feeder - fall hasfell! Winter coming soon.
