// depth = The thickness of the mounting hole mask. Default: 5
// l = The length of the slots, for making an adjustable motor mount. Default: 5
// 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`
// $slop = The printer-specific slop value to make parts fit just right.
// Extra Anchors:
// "screw1" = The center top of the screw hole/slot in the X+Y+ quadrant.
// "screw2" = The center top of the screw hole/slot in the X-Y+ quadrant.
// "screw3" = The center top of the screw hole/slot in the X-Y- quadrant.
// "screw4" = The center top of the screw hole/slot in the X+Y- quadrant.
// Example:
// nema17_mount_holes(depth=5, l=5);
// Example:
// nema17_mount_holes(depth=5, l=0);
