Track Connector – Hot Wheels Track Builder Compatible

🧩 Description

Universal connector for 1:64 scale HWTB tracks, fully compatible with Hot Wheels Track Builder.

Designed for a tight, reliable snap-fit with softened transitions to reduce stress and help prevent cracking at the joint.

Works also with most community tracks.

🖨️ Printing Orientation & Tips

Orientation: Lay flat on the bed (do not print on its side).

Supports: Not required. If you want a perfect cosmetic underside, you may enable light supports — functionality doesn’t need them.

Adhesion: Add a small brim if your bed is slick.

Fit tuning: If too tight/loose, adjust Horizontal Expansion ±0.05–0.15 mm instead of scaling the whole model.

Filament care: Keep filament dry; a well-tuned first layer improves snap-fit accuracy.

🛠️ Recommended Settings (connector)

Layer height: 0.20 mm

Walls / perimeters: 8

Infill: 33 % (Gyroid)

Supports: Not required (cosmetic optional)

Brim: Optional

Filament: PETG (recommended) or another strong, slightly flexible filament.

PLA is not recommended here — it tends to crack at the snap/transition zones.

Adhesion: PEI smooth or textured sheet with glue stick or another adhesion aid recommended
