Tablet holder extension

These constructions are additions to the tablet car holder created by user: DANY112SVK.I have designed for a car: BMW X3 Type F25. It's possible that it will work for other car fans too.For the original screw connection=tablet_part1, I constructed a ball mount for the fan carriage.The thread type is "metric ISO trapezoidal thread".Everything can be printed with ABS filament.I don't need CDs, because I have a tablet with bluetooth connection, so I hear music from the tablet.Therefore a stabilzer is installed, which reduces the tablet vibrations.
