M8 threaded wing nut and threaded bolt with 8mm square hold for snare stand. MUST FINE PRINT on the longest angle across the thread with 100% infill and remove all support on the female thread. it will waist more PLA on the raft and support than the part uses so may as well get a steel one from amazon, it will get to you quicker than you can print it and you still have to run a tap & die over it VERY carefully.
