The cutting tool uses pins to fit parts together.
Pins can only be printer without support in vertical direction.
Pins are brittle and not very strong.
Adding slots and chamfered fins to the cutting tool would give:
much stronger binds,
easy to print vertical AND horizontal without support,
faster to print than little pins,
less to non cooling issues that little pins have,
act as guide to find exact position,
much more surface for glue.
