Original model from bulbasaur0 was beautiful, however I prefer different location of the connection pins on the flipped version (see the photo). Also, the placement was too tight so I've tweaked the external dimensions a bit. 

Please note, that the original author made a plenty of options to choose from, and I have remixed only one, to suit my needs.

Update: in the version 2 the height was decreased (1mm) to allow the better fit, and the technical holes were removed.
