VW MK7 GTI Aero Parts

Description

3D printable aero parts for the VW MK7 GTI. Diffuser fins are currently avaialble, more parts will be added soon.

3D Printing & Installation Instructions

Diffuser Fins

Overview

The following hardware is required to mount the fins:

  • 6 x M3 x 25mm screws
  • 6 x M3 x 16mm screws
  • 3M molding tape, or any automotive tape. I used this one.
  • Philips head screwdriver that is atleast 5 mm long
  • Ruler
  • Marker

Step 1:

Print 6x diffuser fins using the file provided under DiffuserFin/DiffuserFin.stl. It is recommended to print using PETG since it has the best UV resistance properties and will not discolor. ABS can also be used.

Recommended print settings:

  • 40 mm/s print speed
  • 25% infill
  • Support off

Step 2:

Stick 3M tape on the side of each fin and remove any excess tape.

Step 3:

Clean the diffuser, making sure there is no debris or dust that can inhibit adhesion.

Step 4:

Measure from the top corner of the diffuser and mark a point at 108.5 mm. From that point, mark 5 addition points incrementing by the same distance. These points will be used to align and equally space out the fins:

Step 5:

Remove 3M tape from the fin and align it with the middle of the point created, making sure the fin is perpendicular to the ground. Repeat for the 5 other fins.

Step 6:

Use the M3 x 16mm screws to screw the top of each fin into the diffuser. Then using the M3 x 25mm screw, screw the bottom of each fin.

Step 7:

Verify that the fins fit well and are flush with the diffuser.

Upcoming parts:

  • Add front dive planes (canards)
  • Add rear bumper spats
