The New Hotness

  • Fitbit Charge 5 Charging Stand

    My Fitbit Charge 5 has become fussy about its exact position while snapped to its magnetic charger, so I thought elevating it above the usual clutter might improve its disposition:

    FitBit Charge 5 stand - installed
    FitBit Charge 5 stand – installed

    The Charge 5 now snaps firmly onto its charger, the two power pins make solid contact, and it charges just like it used to.

    The solid model comes from Printables, modified to have a neodymium ring magnet screwed into its base:

    Fitbit Charge 5 stand - solid model section
    Fitbit Charge 5 stand – solid model section

    Which looks about like you’d expect;

    FitBit Charge 5 stand - added magnet
    FitBit Charge 5 stand – added magnet

    A layer of cork covers the bottom and it sits neatly atop the USB charger.

    The OpenSCAD source code punches the recesses and produces the bottom outline so LightBurn can cut the cork:

    include <BOSL2/std.scad>
    
    Layout = "Build";       // [Build, Base, Section]
    
    module Stand() {
      difference() {
        left(38/2) back(65/2)
          import("Fitbit Charge 5 Stand.stl",convexity=10);
    
          down(0.05)
            cylinder(d=12.5,h=5.05,$fn=12);
          up(5.2)
            cylinder(d=3.0,h=10.0,$fn=6);
      }
    }
    
    //-----
    // Build things
    
    if (Layout == "Build")
      Stand();
    
    if (Layout == "Base")
      projection(cut = false)
        Stand();
    
    if (Layout == "Section")
      difference() {
        Stand();
        down(0.05) fwd(50)
          cube(100,center=false);
    }
