Only under warranty Oculus Quest 1 can get a replacement of the Eyeglass Spacer, it should be available on the store so someone like me can buy it (No third party sell the Eyeglass Spacer).

Another idea is to have the 3D Model of the Eyeglass Spacer for Oculus Quest 1 so it can be 3D printed, there is available for free for Oculus Quest 2 here is the link https://www.thingiverse.com/thing:3729871.

I am posting this because I tried by all means to get it from Oculus Support but it was impossible.

Hope this idea can help other customers with the similar problem that I had.

Best regards
