DIY installation

Replace the original declumper of your DF64 and reduce clumping and retention.
This is a marked improvement over the original silicon declumper.
Material used for the membrane is PET (food safe, and it does not leech any poisonous or harmful chemical into coffee).
Spacer is made of environmentally friendly and food safe PLA plastic (coffee seldom comes into contact with the spacer anyway).
