The tube cutter I have (one of Chris Michelssen's but it is similar to the Kuhn cutter currently available) with a fresh blade made cutting a ring that small not terribly difficult.

Then, a ply disc from Semroc inside with a screw eye made a functional replacement part that looked right on the outside.
I had thought about replicating it that way, too. But Bruce Levison ('teflonrocketry1') is working on 3D printing--among other things--the Centuri #13 (Estes BT-56) plastic tubing connector that was used in the Centuri Phoenix Bird and the Enerjet 1340 Sounding Rocket.
