The Apollo class is something of an enigma in Star Trek history, with more than one design being put forth as this class of starship.  What you see here is a fan design of a likely candidate, given the canon registry numbers for this class.  Much like the relationship between the Galaxy and Nebula class ships, it's reasonable to guess that there were similar compact designs based on the earlier Ambassador hulls in the mid 24th century.

The Apollo class is a 6-piece resin 3d printed model in 1/2500 scale, measuring roughly 7 inches in overall length. Model is hollow to save on weight and resin, and is highly detailed. A comprehensive decal sheet is included with your choice of three Apollo class starship names.

Note on the auction: The photos of the Enterprise C and Enterprise D alongside the Apollo is for reference only.  Auction is ONLY for the Apollo class.  Model is unfinished and unpainted.

*A note about 3d printed resin models:   All 3d models will have small "bumps" from the printing support structure that you will need to sand off; this is best achieved with simple padded nail sanding files or modeler's sanding sticks.  The 3d printed resin models I sell are washed in 99% IPA and cured under UV light before shipping, but you may want to allow them to sit in the sun or under a UV source for 5 minutes or so for final post curing if you feel there is any tackiness to the resin surface (there shouldn't be).  All resin models, regardless of design, should be washed with a mild abrasive such as Comet or Barkeepers friend before priming and painting.*
