Centering Rings for Estes Pro Series II 2" Body Tube to Estes 29mm Motor Mount. One STL is plain, one has cutouts for 1/8" tubing used as staging wiring chases and notches for anchoring shock cord to the motor mount. I print them in pairs and glue them back to back for a thicker centering ring. The outer rim provides plenty of body tube contact. I've flown these on an H53 flight.
