Hi all,
I designed a model that fits every tablet, held by the two car headrests.
The lock mechanism is double, Printed in one unit.
It is very easy to use, and turns over to the passenger side easily.
Adapted and designed to a broom stick.

dimension:
Rod, stick - up to Ø25mm
tablet:
width up to 160mm
thickness up to 11mm (Upper side with lock, recommend to apply a piece of sponge to the bolt)
Length does not matter

So Enjoy the quietness of the children in the back seats
:-)
