Cold Brew adaptor for Aeropress coffee maker

thingiverse

The parts combine with a sports-style water bottle to form a cold brew attachment for the Aeropress coffee maker, consisting of three distinct components. These are: 1. A bottle holder that attaches the water bottle to the Aeropress, requiring only the cylinder part of the device and not the piston portion. 2. A drip spreader designed to prevent drips from forming a tunnel through the grounds, ensuring even extraction by coming into contact with both coffee and water. The drip spreader must be made of food-safe filament such as polypropylene due to its direct interaction with these substances. 3. A lid that serves an optional purpose, keeping dust out of the brewing water while it is in use.
