Parameter overview

  • The total thickness of the vent is 25 mm.
  • Whatever the parameters, the slats never overlap. This ensures an optimal airflow. At the same time, the slats form an almost opaque screen along the axis.
  • The slats are actually shaped as parallelograms rather than rectangles. This ensures better printability.
  • The slats and the central reinforcement (if present) feature a 0.40 mm fillet on all edges. This improves airflow and prevents potential whistling.
  • The collar, if present, is 3 mm thick and has a 2 mm fillet for aesthetic purposes.
  • The male insertion area is 3 mm thick and has a 1 mm fillet on both edges to facilitate insertion into the intended slot.
  • The central reinforcement, if present, is 2 mm thick and spans the entire projected width of the slats.
