A universal tablet mount which attaches to car seat headrest posts.
When my daughter gets antsy on long car rides, sometimes we allow her to watch TV shows on a tablet to keep her entertained. Until now, I always just held a tablet up for her to watch, which was obviously less than ideal. She sits in a rear facing car seat, so I decided to design a tablet mount to attach a tablet to the headrest posts for easier and more comfortable viewing. This mount can also be attached to the headrests of the driver or passenger seat facing rearward for people sitting facing forward in the rear seats.
This mount will hold tablets up to about 215 mm in width (12.9 in iPad Pro).
This mount was designed to be easy to print and does not require any supports. I printed all parts in PLA for ease of printing, however PETG or ASA should be considered if you plan on leaving it in a hot car in the summer.
Only qty. 4 M3x8 screws are needed for assembly. Please do not over-tighten any of the printed nuts or the M3 screws to avoid damage. They just need to be snug.
