thinwall_20_30
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](https://reprap.org/wiki/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 <Round-Anything-1.0.4/polyround.scad> // 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.
