Fits standard 70mmX18mm rocket engines A, B and smaller C
Haven't shot one off yet I doubt you will recover it. Fair chance it wont survive the parachute eject stage. No parachute one solid piece.
Edit: Now I have tested them and they fly. When the eject stage hits it pops the motor out so if you colds mange to stuff a ribbon in there recovery is possible. Depending on your print settings the motor may fit a little too loose. A single wrap of electrical tape around the motor seems to do the trick.
