SIM racing tablet mount

Made this for a friend's SIM racer.

Tablet mount is based on this design: https://www.thingiverse.com/thing:3033578

Ball ends are based on this design: https://www.thingiverse.com/thing:1282392


Seems pretty strong and holds even this huge tablet.

Used a M8 threaded bar between the ball ends.
4x 3x 20mm screws for stoppers
M8 screw for the arm
M5 screw and nut for holding the mount
M4 screw and nut for the slider
large washer below the arm, smaller one that fits into top of arm

Arm is 50% filled, 30% should also be enough.
Used my A30 for the black and the i3 mini for the green parts.

Update 13.8.21: as per request, I added an STL for a shorter arm (200 mm)
