Description

UPDATE 2: As requested, a remix using bolts to assemble https://www.thingiverse.com/thing:3431139 UPDATE: I modified the base piece to allow for side-to-side adjustment during installation (see red printed piece in photo). For my car, the mechanism works best biased towards the driver's side, hence the original asymmetrical design. Based on user feedback, the original design can rub against the striker on some cars, so the new design allows you to position the mechanism best for your particular car. Locking mechanism for Tesla Model 3 rear seats. There are 2 versions of the "rocker arm", one for a simple toggle, and one for the extended linkage. Video of operation, assembly, and installation: https://youtu.be/8tt10vhaUjw Edit: Sorry if mixing all the files together was confusing...here is the breakdown of parts (I also added a zip file for each lock type if that's easier):.
