After purchasing a refill kit off amazon, I found it clunky and tedious trying to fill the cups without making a mess and then cleaning the edges before applying the foil all just made for a slow pod refilling experience.

This design is simplified and somewhat aesthetic compared to others I've seen. The tolerances are pretty precise and I was super impressed with how well it ended up working. Hope someone else can get some use out of this!

The tolerances were pretty tight so a small amount of sanding on the lid and base edges that touch made for a much smoother action.
