Modeling using puzzlecad, an open source OpenSCAD library. Source code is also uploaded. Download puzzlecad library, put the \*.scad file into the folder and open it. Then you can easily change size, inset, bevel, etc. Remove the \* before the model (one line a time, add \* back for the next), and press F6 to render, then export the \*.stl file.

Took me less than 15 minutes to solve both sets in total, which I guess, means the puzzle is not hard. But the design is really clever, I enjoyed every minute solving it.
