Wrapping Case

You can create simple containers (cases) for wrapping small items. For example, cases for coin purses or earphone cases.

1. Please set the width and height of the target small item.
2. If you want thin walls, set the thickness to about 0.6; if you want an infill pattern wall, set it to 3 or more.
3. Both sides are created with cylinders. Please set the radius to half the thickness.
4. $fn sets the approximation degree of cylinders in OpenSCAD. Set $fn to 6 or more. If $fn is 6, it will be a hexagonal prism; if 20 or more, it will be a smooth cylinder.
5. When attaching a band so it doesn't protrude from the main body, set band_width to a value greater than 0. If you want the band to be vertical, set virtual to true; if you want it horizontal, set it to false.
6. If you want to generate a cap in addition to the main body, set with_cap to true; if a cap is not needed, set it to false.
7. If you want to create two linked items, set double_size to true; otherwise (this is usually the case), set it to false.

Setting example 1: Coin case

  width = 45;  height = 95;  thickness = 0.6;  radius = 6;  $fn = 20;  band_width = 0; virtical = false; with_cap = true; double_size = false;

Setting example 2: Earphone case (two-tier)

  width = 50;  height = 45;  thickness = 0.6;  radius = 12;  $fn = 20;  band_width = 14;  virtical = true;  with_cap = true;  double_size = true;
