Universal Gunsmith Block / Bench Block

This Universal Gunsmith Bench Block / Universal Gunsmith Block is an indispensable tool for anyone who maintains fine mechanics, needs to drive out pins, or works on firearms (such as the M1911). It serves as a stable base that protects the workpiece while providing cutouts so that the pins can fall through freely.

Key Features:

• Versatile Bores: Various diameters for different sized retention pins.
• V-Groove & Contours: One side features a V-groove for stabilizing round components (e.g., barrels or bolts).
• Material-Friendly: Unlike steel blocks, the plastic version prevents scratches on bluing or coating.
• Center-Hole: Special cutout for working on the mainspring housing.

Print Recommendations (IMPORTANT):

Since this part must withstand mechanical stress (hammer blows), I recommend the following settings:

• Material: * PETG or ASA/ABS: Best durability and chemical resistance (against gun oil/cleaner).
  • TPU (95A): An interesting option for a particularly non-slip and extremely gentle version.
  • PLA+ / Tough PLA: Possible, but more brittle with hard impacts.
• Wall Loops: At least 6–8 lines. Stability here primarily comes from the walls!
• Infill: 40–60% (Grid or Gyroid for maximum compressive strength).
• Top/Bottom Layers: At least 5 layers to achieve a solid striking surface.

Legal Notes & Safety:

• This is an independently designed tool to assist with maintenance work. It is not a functional firearm part.
• Use at your own risk. Always pay attention to safety when working on mechanical devices and use high-quality tools (punches).
• Please check the stability of your print before use to avoid damage to the workpiece.
