The inner discs are actually smaller, just to be safe: 40 and 23mm.

I made this from scratch in tinkerpad, but I was inspired by the https://www.printables.com/model/475853-bb86-bottom-bracket-press model, which is probably very similar, only it is suppose to work with a thicker rod than I had. Also, the writing on the bottom slows down the print - the side one in my model does not, but it is not visible either :))

With a .8mm nozzle, .4 layer height, 24% infill and 30mm/s print speed, it took about 50 minutes to make one.
