This is a replacement model that closely resembles the Tesla part number 1004039-00-B. It is not an exact clone!

Known in the electronic parts catalog as: INSERT WEDGE DAMPER, LIFTGATE 1004039-00-B

It was missing on one side of my trunk, causing it to sometimes get stuck while trying to open. The part is very cheap at Tesla, just order it (€8 for 2)! If you want to print it anyway, here's an option to do so.

Highly recommend to use PETG with high (if not 100%) infill. PLA will warp in high heat! And give it at least 3 walls, just to be sure.
