A removal tool for non-standard large G9 socket rings. This particular one is 12-toothed, so make sure that your socket ring is the same spec before printing.

As shown in screenshot three, the inner diameter of the key is 30mm, and the outer is 31.4mm. The particular socket I use this with has an M28 thread.

Should be compatible with most rings, but I have also made a ring that is guaranteed to work with this tool: [https://makerworld.com/en/models/1069344](https://makerworld.com/en/models/1069344)
