This is the shuttlecraft Hyonos of the USS Quasar, a Type-17 shuttle. It was made as a paid commission for a SciFi-Meshes.com user.
The design is based on a design study made by Rick Sternbach in 1990 for 'Star Trek: The Next Generation'. The study was eventually abandoned due to budgetary reasons, as it was cheaper to re-use a shuttle made for the production of 'Star Trek V'.
