I had a moka pot. Everytime after filling 2 tablespoons of grounded coffee. I had to use the spoon to press or compact the coffee powder. So I design a simple design to enable even and firm compacted ground coffee. How it help out you guys there. No more time consuming pressing with table spoon. And it cost so much lower than those press found in market place. Cheap. Simple. Practical. Love it and using it myself. Hope you guys enjoy it.
