My son has this particular tablet case with a handle and wanted an easy way to watch it in the car. I took the profile from the original model and made it height adjustable with a big hook to put the tablet handle over.
It never falls of, even when accelerating hard like one tends to do in a new Tesla. Never tried full plaid though.
Screw the hook to the plate with 3 mm wood screws and slide the plate into the mount. The mount should fit over the back of the front seats in the Model Y and older Model 3.
Hope your kids will enjoy it!
The author remixed this model.
Remodeled the profile completely to create a height adjusting feature.
