Aeropress Adaptor - Stepped Reducer for small cups
Available for purchase here on Shapeways:
https://www.shapeways.com/product/K3H...
This adaptor allows you to use your aeropress with smaller cups. Perfect for tiny espressos or reusable cups like the Frank Green, which doesn't quite fit an Aeropress. It fits over the black filter holder and sits between the Aeropress and your coffee cup.
Please note that ABS is not considered food safe, and you should coat the adaptor with a polyurethane or epoxy finish. These are readily available in a hardware store (look for 'salad bowl' finish) but can take up to 30 days to cure properly. If only Shapeways offered PLA prints for sellable products.
