What are the dimensions of the Model 3 tow hitch door?

Just a word to the wise for Model 3 owners. Do not get a tow hitch. I wanted to install the hitch on my model 3 for a bike rack. No company will install it, Tesla says it voids the warranty. No I'm out a bit of money on the hitch and the bike rack.

Considering that Tesla actually offers hitches on the Model 3 as optional equipment (such as in the UK), their claim that it voids the warranty smells like bovine feces.
 
Put a hitch on both of my model 3’s, and the egolf before that. EV’s tow great, but you only want a bike rack, so leave off the wiring and chain mounts (stealth hitch).

It doesn’t “void the warranty” in the US - the manufacturer would have to prove the item caused a failure of some sort - for example the hitch (made of steel) mounts to aluminum. Improperly installing the hitch without the plastic isolators will cause the aluminum to corrode. This would definitely void a warranty corrosion issue.

Dimensions include a curved side. Width is 17 11/16
Height max 6 3/16 min 5 5/8

No mm tools handy. The minimum height has a radius and may be off.

But I made my own version using four cabinets door magnets to attach the new tow hitch cover to the older diffuser.
