Code

From woodwright/examples/joints.py, which imports the names it uses (see From an example to your own design):

def mitre_splice(
    length: float = 300, width: float = 40, angle: float = 45, stock: Stock = OAK
) -> Assembly:
    """Two stiles end to end, lengthened by a mitre across the face."""
    asm = Assembly("mitre_splice", root_location=STANDING)
    a = asm.add(Board("a", stock, length=length, width=width))
    b = asm.add(Board("b", stock, length=length, width=width))
    asm.join(MitreSplice(a.right_end, b.left_end, short=a.back_edge, angle=angle))
    return asm
