Ergonomic handle
thingiverse
<body>These handles are actually part of a bigger project I'm working on, but it's so non-standard-parts-specific that it doesn't worth the effort of publishing the entire project by itself. I first designed the handles to fit pre-made holes on a aluminium heat dissipator, but later, I adjusted it to fit in given percentiles, so it can be truly "ergonomic". The original one has a hole to hole distance of 10cm, and it fits the percentile 1 of male's hand, and 75 of woman's (_m01_w75); the second one has a distance between the screw holes of 11cm, and it is for percentile 35 for male and 99 for woman; the bigger one has a distance of 12cm and a percentile of 99 for male. These values are those for hands fitting <b>comfortably</b>, bigger hands could use it anyway. For those who don't know about percentiles, lets say that, for a given population, a <i>P</i> percentile corresponds to an <i>X</i> body part size (or weight) if <i>P</i>% has that part size smaller than <i>X</i>. If you know about this, these values are upper values for the handle width, but the bigger one can be too wide for the smaller hands. All percentile's data was taken from the book <i>The Measure of Men and Woman</i> by Alvin R. Tilley and Henry Dreyfuss, for adult men and women. <h4>References</h4> <ul><li>Tilley, A.
