Pretty cool project. Thanks for the share!
As would be expected, it was labor intensive to remove support material but overall, I think it took half an hour for the one piece that I made.
Piece also took longer than estimated by software by a considerable margin. If I were to make it again, I'd try with the smaller nozzle as the pieces don't fit together well on the bottom. Perfect on the top of the piece.
