Small details,
big difference on the bike.

PETG.

A tough engineering plastic that doesn't go brittle in winter or soft in a hot car. Holds up well to UV. Good impact resistance. Each mount is printed as a single piece — no glue, no seams.

• Works from sub-zero to summer heat
• UV-resistant material
• Impact-tough, not brittle
• One piece — no glued seams

Tight layers,
right direction.

Printed with adaptive layer height 0.08–0.2 mm — thinner layers where the detail is, thicker on the flat runs. Precise where the geometry asks for it, sturdy without wasted print time. Direction is chosen so load runs along the layers, not across them — material strongest where the forces actually go.

Zip ties built
for the outdoors.

Hardware-store zip ties dry out in the sun and snap in the cold. The ties that ship with each mount are 2.5 mm × 200 mm, rated UV-resistant and made for outdoor use. Tightened down they sit slim and tidy.

• 200 mm long — easily clears a vent slot
• 2.5 mm — tidy but strong
• UV-rated, outdoor-grade
• Adds ~1.3 g after trimming

Black dome cap nut,
already in place.

Each mount has a seat shaped for a DIN 1587 dome cap nut — black, zinc-plated carbon steel. The rounded cap covers the screw thread, and the black sits next to both the mount and the GoPro: a combination that looks right and doesn't just function. I press the nut into the seat before packing — a tight press-fit, no glue needed. The zinc finish helps resist corrosion in outdoor use.
