Hook for a power extension cord

thingiverse

This is a fully parametric model (in Autodesk Fusion 360) for a hook to support a power extension cord - mostly for outdoor applications (e.g. to thread an extension cord along your fence, or wall). Designed for standard drywall screws, can be adapted for any other countersink screws. You'll need to print a bunch of these for a typical scenario. Important parameters: - wire_diam : the electric cord diameter. Should be slightly larger than the actual diameter, to make sure the cord can be inserted with not-too-much effort, and would stay there securely. - delta: affects the opening gap for the cord. It's not the actual gap, as the actual gap is affected by the fillet effect. You can measure the actual gap inside Autodesk (see the attached image; the number you need is the bottom one - 7.142 mm on my image). If the actual gap is too large, decrease the "delta" parameter; if it's too small, increase it. - head_diam, head_height, screw_diam: countersink screw parameters. I printed this in ABS as it's an outdoor application. I used 40% infill and 1.2mm walls for strength.
