So, I came up with the name "thimble" The reason being is because DIYer's specifically more on the sewing/craft side use thimbles to protect their fingers from harm. I though it would be a good metaphor for them trying to protect the planet. I hope it's not too crafty though. It's difficult to find the right coded word for the name of this. I feel I have to be careful and not go too far into the green movement, because it's not specific to the DIY group.
