// Creates a shape that you can use to round 90 degree corners.
|

// Difference it from the object to be rounded. The center of the mask
|

// object should align exactly with the corner to be rounded.

// Arguments:
|

// r = Radius of corner rounding.
|

// d = Diameter of corner rounding.
|

// anchor = Translate so anchor point is at origin (0,0,0). See [anchor](attachments.scad#anchor). Default: `CENTER`

// spin = Rotate this many degrees around the Z axis after anchor. See [spin](attachments.scad#spin). Default: `0`

// orient = Vector to rotate top towards, after spin. See [orient](attachments.scad#orient). Default: `UP`
