Door lock insert for VW Polo 6N and other VAG cars

Quite a few 1990s VAG cars including VWs like my Polo 6N and SEAT and Skoda cars share the same lock mechanism which fails. This is a replacement insert and a tool which may help compressing the spring.

This is best considered a get-you-going part, I strongly suggest buying the repair kit instead for the metal part. Printing it in PLA may result in a part that fails prematurely. But if it gets you out of a hole for a week or two then it's useful.
