Bring that iconic 1960s and 70s European roadster and sports car look to your retro 80s BMW E21! These custom-designed 3D-printable mounting plates allow you to cleanly mount classic Raydot-style round mirrors directly onto the factory E21 mirror triangle geometry.

Features

  • Designed specifically to fit the OEM E21 mirror triangle mounting points.

  • Adapts classic round Raydot mirrors onto an 80s chassis for a timeless motorsport look.

  • Clean fit, matching the car's original trim lines.

Hardware Needed

  • 2x Heat-Set Inserts (per plate, as shown in photos)

  • OEM mounting hardware/screws for the door triangle

  • Bolts to secure your Raydot mirrors to the new adapter plates

  • RTV Silicone (optional, recommended around the perimeter edge for weather sealing against rain)

Print Settings & Recommendations

  • Material: ASA or ABS is strongly recommended for UV and temperature resistance since these sit right out in the elements. PETG is a good alternative.

  • Orientation: Print flat with the mounting side facing up.

  • Perimeters/Walls: 3 to 4 walls for optimal strength around the heat-set inserts.

  • Infill: 20% to 40% (Grid, Gyroid, or Cubic).

Happy building, and make sure to share photos of your E21 with the classic setup!
