It is interesting that you fancy the MIRANDA class Federation Starship. When I was starting scratch building paper/cardstock models, the U.S.S. RELIANT was the very first (STAR TREK related) starship that I built (unfortunately, I no longer have it).I'll need to have a good root around in the resources one day, but there's so much already printed out to catch up on
You can't or Khan't go wrong with a Miranda class, one of my all time favorite Star Trek ships - I find the NX-01 a bit flat, nice, but squashed
With that being said, there are a few good templates of the MIRANDA class Federation Starship available (both in the resource section and on the internet).
