Configurable triangular coffee capsule holder

A three-sided generic coffee capsule holder. I needed a coffee capsule holder for my Portuguese Delta Q capsules and most of the models I could find were for Nespresso or Dolce Gusto, hence this design. It fits 12 capsules (4 per side) because that's the amount after which I need to remove the capsules from my machine. Capsule parameters and size can be changed on the beginning of the openscad file.

PS: this is also my first design, so feel free to comment and suggest improvements.
