Magnetic mount for depth gauge manual level the bed. The hole diameter is .250 for the depth gauge. Link for magnet is below.
Note: Make sure you have your printer in a spot its going to stay. These big printers like to flex and don't put any pressure on the bed or frame when leaning into the printer to adjust the screws. Start from the middle of the bed adjustment screws and move your way out. I had couple screws that didn't have no adjustment to them, so I put my zero off those. Heat your bed up also when your doing this also.
