LEGO has had many different themes over the years, and Space was one of the very first! M:Tron only came later though, but it's still one of my favourite LEGO Space subthemes! ;o)
Download the parts and instructions to build your own papercraft LEGO M:Tron astronaut (and lots more! ;o) from my papercraft webpage:
See the release video here: link
(and the Blacktron "sequel" here: link ;o)
Have fun papercrafting!
