Model Rocket Centering Ring. Fits a 29mm cardboard motor mount tube into a BT-80 coupler. Does NOT fit into a BT-80 body tube, only a coupler.
I use this to make 29mm avionics bays up in the nose for my eggfinder tracker. My Eggfinder mounting sled is available as a separate 'thing'.
Includes mounting holes for a recovery harness to pass through. Epoxy your recovery line to the 29mm tube, the centering ring probably won't be sufficiently strong enough.
