Europe´s BepiColombo is currently on its way to Mercury, where it will study the magnetosphere.
The paper toy is based on ESA´s “Epic Adventures of BepiColombo” cartoon about the probes.
Some years ago there was a similar project for ESA´s Rosetta probe, which deployed a lander on the comet 67P. I liked the papercraft of it and decided to built one for BepiColombo.
As a papertoy BepiColombo is very easy to build and has only optional details.
