Sadly, in the US, Keurig is king. Nespresso is such a better product, hands down. Instead of printing or designing nifty holders for the pods, I figured I'd make use of what's already here. With these, you can adapt a K-cup carousel or wire holder to carry Nespresso pods.
These should be the final iterations. They are friction fit and may require some sanding. The single lobe inserts will allow you to fill every space in a holder like in the pictures. The double lobe is handy if you still us the K-cups.
