Headrest headphone brace/hook system; now my 4yr old can pickup and place back her headphones on her own even after being restrained in her car-seat. Please verify your installation for safety! Make sure you are leaving enough room between your occupant and the headrest installment in case of a potential collision!! This setup is pretty beefy. It was designed with those that like to power yank on things and contort objects to their limits.Print the two stl's Raise up your cars headrest Place the brace around a headrest pole Slide on the hook Lower headrest Place headphones in hook for a cleaner cab and easy access for childrenThis was successfully printed on a MK6+ TOM @ 30% infill Make On!
