There are several different castings of the Hornady LNL AP press. The older press has a more square bar and the new presses are more trapezoid shaped. There may be 2 different sizes of the clamps that fit the newer presses. The widest one fits the newest presses.

Print with 4 walls, 2 bottom layers, 3 top layers, 25% gyroid infill. If using a 0.6mm nozzle 3 walls is fine.

The mount has 2 different sizes for the dovetail. V1 is for normal prints with calibrated printers and V2 is slightly wider if the dovetail fit is loose. Slicer flow settings can impact the fit between the dovetails.

Will need 2 #8 5/8" screws to secure the clamp and mount to the press.
