These plates were designed for the Lee Bench Plate Reloading Press Mount LEE 90251. One model is blank except for the two rear locating holes. The second model has all the bolt holes for a majority of Lee reloading presses.

I set infill density at 50% and wall, top and base thickness at 2.4mm with no problems
