Like many of my other wine glass designs, this uses a near-ideal tulip shape glass together with a separate stem that can have materials assigned separately. This one is unique in that the stem comes in three parts.
My idea for making it was that a wine glass would look great with a metal stem that had a gem in the middle with subtle, curved faceting.
For ultimate detail, the NURBS data in STEP format is also included alongside the OBJ. For Keyshot users, I have also included the scene data BIP and KLP used for the preview if you quite like that and would want to use it in your project.
