Impossible Dovetail with secret hole

I simply brought it to tinkercad and made a reasonably sized hole that shouldn't compromise the strength of the cube. The customized bottom and original top are in the files.

Just printed it at .4mm layer height and 15% infill. They each took half an hour and came out great. It was a tight fit so i sanded it a little which made it a bit bett
