The New Hotness

  • Floor Lamp Remote Control Holder

    The remote control for the floor lamp across the Reading Room will never again wander away into the clutter:

    Floor lamp remote holder - in use
    Floor lamp remote holder – in use

    The magnet in its back snuggles against a steel disk embedded in the holder:

    Floor lamp remote holder – installed

    A magnetic field visualization sheet revealed the magnet:

    Extract the remote’s profiles with a contour gauge:

    Floor lamp remote holder - pin contour gauge
    Floor lamp remote holder – pin contour gauge

    Trace the outlines and lay smooth curves around them with Inkscape:

    Remote profiles - Inkscape curves
    Remote profiles – Inkscape curves

    They needed a slight lengthening to account for the gauge pin diameter & deflection, but this isn’t a precision project.

    Do the same with a scan of the front face, import the curves into OpenSCAD, extrude them, create a solid model of the remote from their mutual intersection, then add a cylinder to punch the depression for the steel plate:

    Floor Lamp Remote Holder - solid model - bottom
    Floor Lamp Remote Holder – solid model – bottom

    The chonky model corners stick out too far compared to the stylin’ curves on the real remote, but I made the holder shorter than the remote specifically to avoid fussing with such details.

    Subtract the remote from a nicely rounded cuboid and knock out a cylinder for the pipe it’ll mount on to produce the holder:

    Floor Lamp Remote Holder - solid model - Show view
    Floor Lamp Remote Holder – solid model – Show view

    I briefly considered a circumferential clamp around the pipe before coming to my senses and making the pipe diameter 2 mm larger to accommodate a strip of double-sided foam tape.

    The magnet gets a ferocious grip on the plate and I defined the result to be All Good™.

    The OpenSCAD source code and SVG paths as a GitHub Gist:
