Okuma Turret Temporary plug.
My employer just got an Okuma LB3000EXIII and the trainer showed up before we had all of our tooling delivered. We wanted to make some chips but didn't want a bunch of crap getting inside the turret through the uncovered holes. I whipped these up overnight and they worked great. I used PETG with .4 nozzle, .24 layer height. I also included holes for magnets in case they were a little loose but they fit perfectly.
