Original
The original set is at Thingiverse  https://www.thingiverse.com/thing:4387531
It includes an excellent pamphlet giving some background and listing 40 different puzzles of 6 blocks.  It includes a tray for storing the puzzles in.

This Variation
The original offers 3 sets having different notch widths.  I found even the tightest set to be rather loose so I offset the notch faces by 0.07mm. 
As printed they are a bit tight.  Put them in a plastic bag with some talcum powder & shake them up.  It makes the PLA non-sticky & the blocks slide together nicely.

Background
A very good site discussing puzzles http://www.robspuzzlepage.com/interlocking.htm#notchable
It was that site that led me to the Thingiverse set.  
There is another set there of 9 additional blocks.
There are some at Printables.
