title_body: Conversion of Krups Nespresso Machine to Ground Coffee?
upvoted_answer: You could get a reusable nespresso capsule Like this.
  Its a little bit more effort when you want to make your espresso but it would be the simplest and probably cheapest option for you.  But this comes with some disadvantages too, like the capsule can only hold 5 grams of coffee, maybe 6.
