Anker LC40 flashlights can use either one lithium 18650 cell or an adapter holding three AAA cells. I now prefer 18650 cells, but they’re nigh onto 4 mm smaller than the flashlight ID and rattle around something awful.
I can fix that:
Three new entries appear in the cell dimension table of my OpenSCAD inter-series battery adapter program:
NAME = 0; ID = 0; // for non-cell cylinders OD = 1; LENGTH = 2; Cells = [ ["AAAA",8.3,42.5], ["AAA",10.5,44.5], ["AA",14.5,50.5], ["C",26.2,50], ["D",34.2,61.5], ["A23",10.3,28.5], ["CR123A",17.0,34.5], ["18650",18.8,65.2], ["3xAAA",21.2,56.0], ["AnkerLC40",23.0,55.0] // Flashlight tube loose-fit for 3xAAA adapter ];
I took the opportunity of adding OpenSCAD Customizer comments, which means this now works:
The model looks about the same as before, although with a few more sides just for pretty:
That was easy …
