Seeking a 45mm V2 Holy Trainer Ring Purchase

I just picked up my first chastity cage—a knockoff steel v2 Holytrainer. Unfortunately, I went with the 50 mm ring and it keeps sliding down past my scrotum, so now I need to find a snugger 45 mm one. Steel is preferred, but resin should work perfectly too. Let me know if you have an old spare part lying around that you’d like to pass on; it would be great help for a beginner like me.

Are you located in Europe? I have an extra 45mm resin ring from a knockoff brand. Since I own two of them, I'd be happy to send mine over for just the shipping cost if that works for you.

Yes, I'm in Copenhagen, Denmark. That would be fantastic! This is only my third post here, so once it gets approved, I should have DM permissions and can reply directly.
