Hidden Joint - Japanese woodworking joint

I remember seeing this joint drawn out and thought it would make a good 3d print.   Unfortunately i can't remember where i saw it or who designed it so this is my recreation of it based on my best guess.  In any case it's a quick print of a neat hidden joint.   Structurally i  think it would be weak, but for decorative purposes it seems pretty cool.

Printed in PLA, no supports.
