Manufacturing & Assembly Guide

This OEM-style Hamann Competition Wing kit for the BMW E46 M3 Coupe was optimized for the Bambu Lab H2D printer series build volume (340 × 320 × 340 mm).

For smaller printers, additional model cutting and alignment may be required.

Recommended Print Settings
0.4 mm nozzle
ASA or ABS recommended
PETG possible, but less durable for automotive use
Low print speed
5–6 perimeters
30% infill

For best results, use an enclosed printer with stable temperatures.

Assembly
All wing sections are reinforced using two full-length M6 threaded rods running through the entire wing structure.

Additional hardware required:
Stainless steel bolts
M6 coupling nuts (25–30 mm)
Epoxy or structural adhesive

Coupling nuts should be glued into the dedicated mounting holes before final assembly.

Finishing

For a premium OEM-style finish:

Fill seams and layer lines
Sand the surface smooth
Apply automotive primer, paint, and clear coat
Installation

Use sealing washers or automotive sealant during installation to prevent water intrusion.
