3D model description

This is a thin wall test with rounded and sharp edges. My slicer says it takes about 0.29m of filament, so it's a cheap test for adhesion, speed, retraction, cornering, dimensions, and thin-wall extrusion.

I printed the rough part in the picture in 2012 on a home-built Wallace, and wanted to print a new one on my new printer, but didn't have the pattern. So I hacked one up based on https://github.com/Irev-Dev/Round-Anything :

```
// thinwall_20_30 -- thin wall test piece, copied from memory
// Uses polyround from https://github.com/Irev-Dev/Round-Anything

// https://www.thingiverse.com/thing:6216210

// Wall thickness
thick = 0.5; // 0.01
// length
x = 30;
// width
y = 20;
// height
z = 10;

$fa = .01; // facet angle
$fs = $preview ? 5 : 1; // facet size
$fn= $preview ? 32 : 64; // facet number

thinwall_rounded();

// x,y,radius
radiiPoints=[
[0, 0, 0 ],
[x, 0, 10 ],
[x, y, 10 ],
[0, y, 5 ]
];

use // https://github.com/Irev-Dev/Round-Anything

module thinwall_rounded(){
linear_extrude(z){
shell2d(-thick)polygon(polyRound(radiiPoints,30));
}
}
```

If you use OpenSCAD, you can customize the dimensions, but the Thingiverse customizer won't work because it doesn't have the library available.
