Have you sent that link to Stephen at Fibrelyte? Possibly they have made a 3/32" track ring for you, if you asked for 3/32" single without specifying that you were using 1×9/10/11. The teeth would be 2.4mm wide for 3/32" but 2.2mm for 9/10/11-speed. Everything I've ever had from them has been spot-on dimensionally, but somebody may have erroneously sent the wrong G-Code to the CNC, either due to confusion about exactly what you were asking for or just dumb error.
