A small car air vent scenter that allows air to blow thru it to scent the interior of your auto. You can use scent beads or even liquid scents that have been applied to a small piece of felt or cotton ball. Clips directly to the air vent slat. Two plates were used so the clip could be printed in .16mm layer height with standard supports and the other plate is the top and bottom that was printed at .20 layer height - no supports needed. Both were printed in PETG
