Better Twist Snap Design in Fusion

3-Second Blueprint (English)

1. Model an 18-degree entry channel leading into a 15-degree twist slot with a 2 mm path offset and 0.2 mm wall clearance.
2. Add two draft tapers so the 3 mm filleted tab slides smoothly into the channel and rides upward as the parts twist shut.
3. Cut 6.4 mm deep flush pockets for press-fit ball plungers that snap into 2 mm detent holes to lock orientation.
