PRODUCT

SHEETPRESS

It is an ideal key holder to use with carabiners. At its ends you can hang glasses, keys, chinstraps. It is attached to the wall with screws. We start from a 5mm HDPE sheet. *in the how to section, you can find how to make a recycled plastic sheet with various methods. Otherwise, in the bazaar or in the precious plastic network you can find someone to buy from.

    Ready set go

    Download the attached .dxf file and choose a 5mm thick sheet. Cut with cnc CNC Router. *If this is your first time, we recommend using a 1-edged 4mm diameter mill for cuts. To make the bending, it is ideal to use a composite aluminum bending mill at a max depth of 3 mm

    Folded

    Release all the pieces of the sheet and fold using a heat gun. Heat the area on both sides and push using a wooden rod or some other material that does not stick to the hot piece. Prior to this, make the wooden mold as seen in the image to cool, making two cuts the width of the key hanger.

    Placement

    Make two holes in the wall and use the necessary fixing elements according to the material to be drilled. First the part with the perforations must be fixed to the wall and then the second part must be embedded. To place the horizontal we must thread from one of the sides, through one of the inserts. Clever! The horizontal piece that holds the keys will not come off because it has a small grimace that prevents displacement. Enjoy the key hanger

    Hang what you like

    Well, we already have the key hanger hanging! Now we can be creative and hang whatever we want. In these images we show you what we usually hang. Keys, with or without carabiner, facemasks, helmets, glasses, padlock. The key hanger is very practical and allows us to have what we always use within reach. We hope you share with us how you use it.

    Regards from Necochea, Argentina. Necologica.

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].
