I created custom-fit trailer mirrors for the Tesla Model X (from 2021). Maybe these will also work for older Tesla Model X models.
I scanned the exterior mirrors of the Tesla Model X with a 3D scanner and integrated them into my 3D model. I have a 2.30 m wide caravan and with these trailer mirrors I can easily see the back corner of the caravan.
I created these trailer mirrors because the Tesla Autopilot (cruise control) with my old additional mirrors repeatedly recognized a motorcycle and initiated braking.
The cruise control works wonderfully with the trailer mirrors I created myself.

The following material is required to rebuild:
4x M6 nuts
4x M6 screws with a length of 40mm
1x mirror set of 2 https://www.amazon.de/dp/B094TR9HNX?psc=1&ref=ppx_yo2ov_dt_b_product_details
PETG filament
sandpaper

I added a pause in the print. During this break, the support structure must be removed from the nut cutout and the M6 nut inserted.

Of the mirrors purchased, only the mirror glass module is required.

To ensure that the Tesla's original exterior mirrors are not damaged, the inside of the trailer mirrors must be smoothed with sandpaper.

The original Tesla exterior mirrors are always installed slightly differently. It is possible that when folding the exterior mirrors with the trailer mirror at the bottom, a corner hits the trim. This corner should be sanded down a bit.

Have fun with it.

I am not liable for anything.
