    Ready set go

    Download the attached .dxf file and select a 0.2-inch (5 mm) thick sheet. Use a CNC Router for cutting.

    *For first-time users, a single-edged 0.16-inch (4 mm) diameter mill is recommended. For bending, use a composite aluminum bending mill with a maximum depth of 0.12 inches (3 mm).

    Folded

    Detach all sheet components and fold them with a heat gun. Heat both sides and press with a non-stick tool, like a wooden rod. Beforehand, prepare the wooden mold shown in the image to cool the piece, making two cuts the width of the key hanger.

    Placement

    Drill two holes in the wall and use appropriate fixings based on the wall material. First, attach the perforated part to the wall, then embed the second part. Thread the horizontal piece from one side through an insert. The horizontal key holder remains secure due to its design. Enjoy your key hanger.

To create the key hanger described in the tutorial, the following tools, software, and materials are required:

Tools

  • CNC CNC Router (for precision cutting)
  • Single-edged 4 mm diameter mill (suitable for first-time users)
  • Composite aluminum bending mill (3 mm max depth)
  • Heat gun (for folding HDPE components)
  • Non-stick tool (e.g., wooden rod for pressing heated plastic)

Software

  • CAD software (AutoCAD or similar for .dxf file preparation)

Hardware/Materials

  • 5 mm thick HDPE sheet (primary material)
  • Wall screws and anchors (material-specific fixings)
  • Threaded insert (for horizontal piece assembly)
  • Wooden mold (custom-made for cooling after bending)
  • Carabiner (optional, for hanging items like keys)

The tools and materials focus on shaping the HDPE sheet and mounting the final product securely. Hardware selections depend on wall type (e.g., concrete vs. drywall). No specialized software beyond CAD is mentioned, though CNC CNC Router control software may be required[1][2].
