Opel Ascona B / Manta B Dash Center Air Vent Back Piece

Replacement dashboard center air vent back piece. It is not exact like original. To ease printing I made it little bit different shape. Use original butterfies and rings. Tape around the oval piece and fill the V-shape with sealant (example Sikaflex 211). Glue with same sealant air vent to dashboard. Use original rings without butterflies to center holes during gluing. After sealant is cured, take tape away and put the butterflies to rings.
