This is the colony ship "SS Conestoga" from the Enterprise episode "Terra Nova". I estimate this ship to be 220m long, to be big enough to carry 200 settlers and their supplies needed for a 9-year flight and the founding of a new colony on an alien planet. This size also nicely fits to the supposed deck hight that can be estimated by the visible windows at the front. Also, at this size, the docking ports on both sides of the forward hull are approx. 2m in diameter, like on most other Earth/Starfleet vessels.
If you need this in another material, size, or quantity, send me a message. I will try to make it as you need. Be sure to read my comments below my shop page
