SampleBox

这是一个简单的盒子，可以自定义尺寸，只需指定内部尺寸即可自动生成合适的盒子

```

tkns=1.5;

innerRounding = 2;

ofs=0.1;

innerSize=[47.5, 62, 16];

boxHolderOfs = 0.5;

holePos = 34;

holeD = 9;

innerOfsSize = innerSize + [0.2, 0.2, 0.1];

boxSize= getBoxSize(tkns, innerOfsSize, ofs)+[0,0,0.1+tkns];

// 盖子

zmove(innerOfsSize.z+tkns+0.2+tkns*3)

boxLid(tkns, innerOfsSize, innerRounding, false, ofs);

// 盒子

difference() {

  box(tkns, innerOfsSize, innerRounding, ofs);

  // 开孔

  ymove(-innerOfsSize.y/2+holePos)

  zmove(tkns+6)

  xcyl(d=holeD, l=boxSize.x+0.2, anchor=BOTTOM, $fn=6);

}

// 安装托盘

xmove(boxSize.y/2 + boxSize.x/2+10)

boxHolder([boxSize.y, boxSize.z, boxSize.x], tkns, boxHolderOfs);

```
