4 roundedCube() v1.0.3 by robert@cosmicrealms.com from https://github.com/Sembiance/openscad-modules
5 Allows you to round any edge of a cube
6
7 Usage
8 =====
9 Prototype: roundedCube(dim, r, x, y, z, xcorners, ycorners, zcorners, $fn)
10 Arguments:
11 - dim = Array of x,y,z numbers representing cube size
12 - r = Radius of corners. Default: 1
13 - x = Round the corners along the X axis of the cube. Default: false
14 - y = Round the corners along the Y axis of the cube. Default: false
15 - z = Round the corners along the Z axis of the cube. Default: true
16 - xcorners = Array of 4 booleans, one for each X side of the cube, if true then round that side. Default: [true, true, true, true]
17 - ycorners = Array of 4 booleans, one for each Y side of the cube, if true then round that side. Default: [true, true, true, true]
18 - zcorners = Array of 4 booleans, one for each Z side of the cube, if true then round that side. Default: [true, true, true, true]
19 - rx = Radius of the x corners. Default: [r, r, r, r]
20 - ry = Radius of the y corners. Default: [r, r, r, r]
21 - rz = Radius of the z corners. Default: [r, r, r, r]
22 - center = Whether to render the cube centered or not. Default: false
23 - $fn = How smooth you want the rounding to be. Default: 128

25 Change Log
26 ==========
27 2018-08-21: v1.0.3 - Added ability to set the radius of each corner individually with vectors: rx, ry, rz
28 2017-05-15: v1.0.2 - Fixed bugs relating to rounding corners on the X axis
29 2017-04-22: v1.0.1 - Added center option
30 2017-01-04: v1.0.0 - Initial Release
