0.4 G Turn Force Meter for Model Y/3.

thingiverse

Sharing this simple 0.4G force turn meter to assist your tesla FSD driving test. Stick this on your rear view mirror housing, and the ball will fall towards center if your turning forces are within 0.4 G. From my experience, the ball will bounce around a bit if you near 0.3G. You will need a 5mm ball bearing, and a full size command strip for attachment. This piece is designed for SLA Laser/LCD printing without internal supports. Not sure how you'd deal with supports with an FDM printer. The tilt of the base is measured from a Model Y, but I assume it will work for a Model 3. Turns out 0.4G is quite a bit, and you can basically drive like a mild madman as long as you keep plenty of space ahead of you and don't trip the overly sensitive forward collision warning. The braking force limit is 0.3G for the tesla insurance calculator, but regenerative breaking will not push you past 0.2G. You drag race at every stop light, floor it on any straight away, and drive 100mph and it won't negatively affect your score (not that you should/need to do that). Made this after trying every G Force and traction meter on my phone without much satisfaction. One app came close (https://play.google.com/store/apps/details?id=oops.speedometerwithgforce) but the indicator was too jumpy. Piece should be like $15 from a 3d print marketplace like treatstock or craftcloud if you don't have an SLA printer.
