A Keurig coffee maker is really neat and efficient method of having your own custom cup of brew, but almost immediately after getting our machine, I could see how the cost of purchasing the K-Cups could add up. Keurig has designed a reusable filter called the My K-Cup, which is a great idea for all the people out there that would like to continue to use their own favorite brands of coffee.
Unfortunately, for the most part, the My K-Cup does not work all that well. Many people have experienced the water leaking back out of the top cap, resulting in diluted coffee or a cup with coffee grinds floating around.
I have come up with a simple modification that will completely cure all the problems with the My K-Cup, allowing you to enjoy your own coffee with no messy leakage of water or grinds getting into your cup. Basically, you need to provide a good seal around the needle as it passes through the hole in the top of the My K-Cup cap. Hopefully Keurig will eventually incorporate some kind of remodel to their product in the future and we will no longer need to do this, but until then here is a list of the few simple tools and materials you will need to tackle this project.
