Quick Armorer Blocks

Make quick armorer blocks with these and a 2x4 or 2x3 piece of wood. They are 5.12 in (130mm) long and 1.24in (31.5mm) wide each. I have used these for armory work for years without them deforming. I have clamped them in vises and used them in arbor and hydralic presses . The latter is what ruined the surface of the green one. But it still works great. Best when printed using ASA/ABS (green and glow in the dark), however, you can use PETG (also shown in red) . I really wouldn't suggest PLA I
