I suggest printing with a raft in the orientation shown in the pictures. Yes, a raft! It gets better bed contact this way and with dialed support settings you get very nice results. It fits the stock bolt. Do not over tighten, this is just for a snug fit to cover the opening. It will not spin unless forced.
