This is a functional Bottle Opener. (Designed for Mechanical Design Contest). this actually works! Easy assembly and little print times. Very satisfying to use! Even if I don't win thank you for such a great opertunity it has been so much fun! Good luck all! Here is a Video of the opener in action: Video Print: Handle: supports - Horizontal Screw: no supports needed - Vertical Body: supports - Vertical Left Wing: no supports needed - Horizontal Right Wing: no supports needed  - Horizontal Settings: Material: I used PLA but you could probably use anything. Retraction: Enabled Print Speed: 60 mm/s Supports: some Infill: 50% on all Assembly: very simple. all you have to is glue the screw to the handle at the bases and insert them into the Body and put both the wings on each side. Thank you!
