// Creates a mask for creating a Robertson/Square drive recess given the drive size as an integer.
// The width of the recess will be oversized by `2 * $slop`.
// The width of the recess will be oversized by `2 * $slop`. Note that this model is based

// We determined the angle by doing print tests on a Prusa MK3S with $slop set to 0.05.
// Arguments:
// size = The size of the square drive, as an integer from 0 to 4.
// extra = Extra length of drive mask to create.
// ang = taper angle of each face. Default: 2.5
// $slop = enlarge recess by this twice amount. Default: 0
