I thought it was Lego at first, but 39000 shapes seemed a bit much. I thought there were only 8-10k shapes?

  mysql> select count(*) from parts;
  +----------+
  | count(*) |
  +----------+
  |    38516 |
  +----------+
  1 row in set (0.00 sec)

Though I'm sure there is some overlap it's definitely not 70%.

That's really shapes and not counting colors/prints multiple times? (Not that it really matters to the scope of the problem ;))

No, if you multiply by colors it gets much worse. 100's of thousands of possibilities...

Of course not all parts exist in all colors so that helps (a bit), but it is quite an interesting problem to work on. Every assumption you make will be challenged.

Prints and stickers are counted separately but that's not a really huge number and they should be correctly identified (so the surface decoration matters as well in the classification).

Do you also plan to detect counterfeit pieces ?
