Tablet holder for rear car passenger

This is a mount for a headrest that allows a rear passenger to hook on any accessories such as a child's tablet. I originally made it to allow my kids to see their tablet on long car rides.

Please note this is not a formally tested product for car rides, and as such, you assume all risks by using this yourself. I'd highly recommend a PETG or stronger filament type given this holds weight and you don't want it breaking in a car situation.

Thanks!
