Round cubes

# Cubes with Rounded Corners for OpenSCAD ## Features * Drops in seamlessly as a replacement for the cube() function * Design and prototype with cube() for rapid preview, then swap it out where needed * Optionally specify a rounding radius for each cube; default is 5% of smallest dimension * Skips rounding of top and bottom faces using the flat_tops module * Cube(x) works with both x as a number and a vector * Use $fn=4 for chamfered edges - great with flat_tops, but may cause some shrinkage in z for round_cube * Round_square is now an option as a 2D shape ## Usage * Copy the rounded_cubes.scad file and add use <path/rounded_cubes.scad> before calling any of the modules ## Example ```openscad use <round_cube.scad> cube([10, 10, 10], $fn=20); translate([15, 0, 0]) flat_tops([10, 10, 10], $fn=20); translate([30, 0, 0]) round_cube([10, 10, 10], radius=1, $fn=20); // For the twist to look pretty $fa = 1; $fs = 0.4; translate([45 + 5, 5, 0]) linear_extrude(height=10, scale=0.8, twist=180) round_square([10, 10], $fn=30, radius=2, center=true); ``` This results in the following output:  ## Known Issues * When the radius is greater than half the minimum dimension of the cubes, it silently defaults to 5% of the radius * $fn value less than 10 can cause noticeable dimensional issues in round_cube()
