Dude, this is an awesome solution. Thanks! : D

Dude, this is awesome. Thanks! : D

I'm printing one right now to try. I've been hoping for a solution to keep my girls' car headphones from getting broken. :)

Good deal!

I snaked the cord through the curve I put on the backside which gives nice friction against the headrest/shoulder of the seat which helps if you have a power yanker. I have seen some pretty aggressive unintentional pull-outs and this somewhat mitigates the direct force on the headphone jack and p

My girl is fairly destructive (why I went to 30% infill) and so far so good; and she actually said thanks cuz it made it easy to hang up/retrieve them on her own after buckling herself up!

She is obsessionally independent for a 4yr old...

Yeah, I went 30% infill on the brace, but I only went 10% on the hook. The brace seemed a little more frail, thus greater infill... the hook is pretty beefy, and I might want it to crush in an accident, thus 10% on the hook. :)

So far, they work great. Thanks again for posting your creation!

Ryguy, I want to start by thanking you for sharing your creation. This is what the 3D printing world is all about.

I want to bring your attention to a very, very, big issue: your headrest headphone hook system is extremely dangerous.
If someone is sitting in the back of your car and you have a car accident, the hook system will very likely crush into the skull of the person behind. I invite you to watch the
following two car crash tests videos and to pay attention at how the dolls move during an accident. These dolls are designed to mimic humans.



Cars from the 50s and 60s (like Cadillacs) used to have big protruding switches for the radio, lights, etc. After an accident, X'Rays often showed people with a switch in their head, and well, recovering was somewhat difficult... This is the reason why nowaday switches in cars are very small. And
I think that this is the reason why car producers don't sell cars with headphone hook systems. It's too dangerous.

I understand that you've put a lot of work in this creation, but I think that you should remove your creation from the websites you uploaded it and also remove it from your car.
yStantz, please do the same.)

I wish you a very nice day and I'm sending you greetings from France.


PS: English isn't my first language, I hope I could express myself in a clear and non authoritarian manner. :)


I would fully agree with you in a no-belted situation and possibly a full size adult shoulder restraint setup but this item was designed for the headrest back in front of a designated 4 point harness car-seat installation. Here is a video of crash testing with a front facing car seat: http://www.
http://youtube.com/watch?v=AjKeq2p8kRYyoutube.com/watch?v=AjKeq2p8kR... Different vehicles have varying distances from 2nd row seating to front row. I originally found mobile video monitor solutions like this one: http://accessories.lincoln.com/screen-asy-9956.htmlhttp://accessories.lincoln.com... that connects to the head rest rails just like my hook and protrudes ev
en further out than the hook but is a factory installable option for our vehicle and licensed by Ford/Lincoln... Our gap is quite large being a Lincoln MKT and puts the hook just barely in full arm extended length of the occupant it is in front of.

I think it needs to be considered on each insta
ll wither or not adding anything to the back of a head rest is valid…

I just put a warning in the description referencing the potential danger before printing and installation just in case.

Hi Ryguy,

Sorry for the delay.

Thanks a lot for your quick and documented answer. Now that you've kindly added a warning people will better decide if they can use the hook or not.

I wish you a pleasant day.

Best regards,
