Modular nespresso capsule holder

I wanted to be able to change the number of sides depending on how many different kind of capsules will be served. Each side is printed in two parts to fit smaller printers. I needed to file a bit to fit the two parts but I preferred a smaller tolerance rather than having a gap. For N sides one needs:
- the matching topN.stl
- N capsuleH_lower.stl
- N capsuleH_upper.stl
- N longPin.stl
- 2*N shortPin.stl
I tested up to 6 sides, for larger towers one might need to increase the infill to make it stronger.
